=History=
 +
==325i==
 +
Being a "standard" E30 model base, the E30 325i was available as a [[Coupe|coupe]], [[Saloon#4-Door|saloon]], [[Cabriolet]] and in later years as a [[Touring]]. Like all models (apart from the "Touring" model), the 325i was available during the "Pre-Facelift" era (known for its chrome bumpers and other touches) and the "Facelift" era (Plastic bumpers).
  
−
'''Standard Specification'''
+
The 325i is considered  the most sought-after standard E30 due to its desirable engine and availability over other models. There are "rarer" models (such as [[M3]] and tuner model cars) but these are serious collectors' items with a price to match. Commonly, people choose the 325i as the E30 of choice.
  
−
'''Options'''
+
During its production run, the 325i was available in all four E30 body types, at the following times:

==325i SE==

'''Common upgrades'''
+
At some point during the E30 production, BMW introduced a trim level known as SE, for Special Equipment, which was only offered to 6-cylinder models (For the [[316i]] and [[318i]], this trim level was called [[LUX]]). This SE package makes the 325i SE a genuine BMW model, which should be shown on the vehicle registration document. The SE trim level was available on all four body styles - [[Saloon#2-Door|2-door]], [[Saloon#4-Door|4-door]], [[Touring]] and [[Cabriolet]].
  
−
'''Production Quantities'''
+
The SE trim level equipped the car with some basic cosmetic options, including [[Interior|interior]] upholstery and [[Steering_Wheels|steering wheels]], plus foglights. Bumpers and valances were colour-coded, and some electric items such as a [[Roof#Sunroof|sunroof]] and [[Doors#windows|rear windows]] were installed. However, the actual SE package changed from year to year, depending entirely on what accessories BMW wanted to include.
  
−
'''Common Problems'''
+
Most importantly, SE cars were entitled to optional extras from the Motorsport list, thus offering LSD, Sports Gearbox and Suspension options to the vehicle, as well as Motorsport body kits. This meant that a 325i SE could be equipped to an extremely high level, far beyond that available to a standard 325i.

 +
As the SE package became increasingly popular, UK dealers planned a new package would equip a standard 325i with the full SE trim level and the best Motorsport items as standard, but only mounted to [[Saloon#2-Door|2-door]] bodies. This car would be known as the 325i Sport, and is a UK-only model.
 +
 
 +
All cars were fitted with LSD as standard, as well as M-Technic bodykits. However, the only way to differentiate a fully-equipped [[Saloon#2-Door|2-door]] SE with a standard Sport is the black headlining fitted to the roof of the car.
 +

There where two models of this car commonly referred to as a "Tech-1" and a "Tech-2". The 'Tech-1' refers to the pre-facelift model and 'Tech-2' refers to the facelift model.

Classic options were the sport gearbox (or automatic sportbox). Also they had the sports interior, which could be fitted with optional materials, including the 'Houndstooth' cotton or a range of leather interiors. Other optional extras were available to the buyers of Sports that weren't available to buyers interested in the "standard" 325i.

The 325i has also been used as the base for the [[Alpina]] C2.7 series of E30s, as well as those of other tuning companies.

The 325i was powered by the [[M20#M20B25|M20B25]], a 2495cc (2.5L), 6 cylinder engine and the largest in the [[M20]] family. Smaller M20 engines could be found in the [[320i]] and [[323i]]. The 325i is commonly fitted with a 5-speed manual gearbox or an automatic gearbox. These engines are known to produce 165BHP-175BHP from the factory.

The 325i had a different suspension setup to the other models (other than the cabriolet and later touring models). The 325i was fitted with 51mm struts as standard, compared to other coupes/saloons which where fitted with 45mm struts. The 325i was also fitted with rear disk brakes (as opposed to drum brakes).

These where available in different models and no model had the option of all of the ratios. For example, the low ratios (2.79, 2.93) where commonly found in the [[325e]] ("ETA", the American economy model) and the higher ratios (3.91, 4.10) where found in the common 325i's and sports. Most of the differentials where available as 'Open', 'Mechanical', or 'Limited Slip'. The 325iX used four differentials.

The E30 BMW 325i is one of the models available within the E30 range, which was considered as their entry-level luxury cars falling under the "3 Series" range, which is a counterpart to their more luxurious models, the "5 Series".

The E30 model, being released in 1984, was continued right through to 1991. Being a "standard" E30 model base, the E30 325i was available as a coupe (2 door, sometimes refered to as saloon), saloon (4 door, sometimes refered to as sedan), cabriolet (2 door with a retractable roof) and in later years was available as part of their touring range (5 door estate model).

The M20 engine was found in the larger engined E30s, whilst smaller engined models used four cylinder engines such as the M10(316/(early)318i), M40(316i/318i) and M42(318iS). During the two eras of E30s (the 'pre' and 'post' facelift eras) the M20 came in two variants, the older is commonly known as the "High Compression" and newer as the "lower compression". There wasn't too much difference in the engines other than compression ratios, radiators and different fittings for various components in the engine bay (this will surely be covered more in a comprehesive wiki on the M20B25).

History

325i

Being a "standard" E30 model base, the E30 325i was available as a coupe, saloon, Cabriolet and in later years as a Touring. Like all models (apart from the "Touring" model), the 325i was available during the "Pre-Facelift" era (known for its chrome bumpers and other touches) and the "Facelift" era (Plastic bumpers).

The 325i is considered the most sought-after standard E30 due to its desirable engine and availability over other models. There are "rarer" models (such as M3 and tuner model cars) but these are serious collectors' items with a price to match. Commonly, people choose the 325i as the E30 of choice.

During its production run, the 325i was available in all four E30 body types, at the following times:

325i SE

At some point during the E30 production, BMW introduced a trim level known as SE, for Special Equipment, which was only offered to 6-cylinder models (For the 316i and 318i, this trim level was called LUX). This SE package makes the 325i SE a genuine BMW model, which should be shown on the vehicle registration document. The SE trim level was available on all four body styles - 2-door, 4-door, Touring and Cabriolet.

The SE trim level equipped the car with some basic cosmetic options, including interior upholstery and steering wheels, plus foglights. Bumpers and valances were colour-coded, and some electric items such as a sunroof and rear windows were installed. However, the actual SE package changed from year to year, depending entirely on what accessories BMW wanted to include.

Most importantly, SE cars were entitled to optional extras from the Motorsport list, thus offering LSD, Sports Gearbox and Suspension options to the vehicle, as well as Motorsport body kits. This meant that a 325i SE could be equipped to an extremely high level, far beyond that available to a standard 325i.

325i

As the SE package became increasingly popular, UK dealers planned a new package would equip a standard 325i with the full SE trim level and the best Motorsport items as standard, but only mounted to 2-door bodies. This car would be known as the 325i Sport, and is a UK-only model.

All cars were fitted with LSD as standard, as well as M-Technic bodykits. However, the only way to differentiate a fully-equipped 2-door SE with a standard Sport is the black headlining fitted to the roof of the car.

There where two models of this car commonly referred to as a "Tech-1" and a "Tech-2". The 'Tech-1' refers to the pre-facelift model and 'Tech-2' refers to the facelift model.

Classic options were the sport gearbox (or automatic sportbox). Also they had the sports interior, which could be fitted with optional materials, including the 'Houndstooth' cotton or a range of leather interiors. Other optional extras were available to the buyers of Sports that weren't available to buyers interested in the "standard" 325i.

The 325i has also been used as the base for the Alpina C2.7 series of E30s, as well as those of other tuning companies.

The 325i is commonly fitted with a 5-speed manual gearbox or an automatic gearbox. These engines are known to produce 165BHP-175BHP from the factory.

The 325i has had many differentials available to it over the years. These include: 2.79, 2.93, 3.23, 3.46, 3.64, 3.73, 3.91, 4.10. These where available in different models and no model had the option of all of the ratios.
