You will all be pleased to know that this car got raped of all its morsels and is still going strong as an M30'd anchor spec car and still owned by a mate...

I know how much the E30 zone loves some drift action ! :)
How do you pronounce 'either'? I say 'either', but some say 'either'. Either is correct.

Raising the gearing(73mph at 3000rpm)will not save you fuel as the engine will be out of it's powerband,so you will be rowing it along on the gearlever.

One of the other two ratios would be better,3.91 perhaps the best choice with a 3.73 perhaps a bit too long....
On the contrary, my 1984 320i with the 3.45 diff drove very well and would buzz to 55-60 in second gear. Was also very good on fuel on a long run.
