Wow....insurance companies are going to love you.
A 21/22 year old with 1-2 years experience, running an 'old bmw' with 'a big engine' is going to produce some brilliant quotes!
It's bad enough insuring a standard 325i cab in my mid 20s (looking at ~700pa) and I've been driving since I was 17 (full license 6 months after 17th birthday). I have a very good postcode, no accidents or convictions in the past few years and 3 or 4 years NCB.
EDIT: When I was running my last E36 I phoned round companies and was given £1200-£2500 quotes because "It's a BMW sir" despite it being a 1.9 i4 and being able to insure hot hatches for £200 or so. I sorted it to 600 or so first year and 340 second year by hunting around mind.
EDIT2: I'd also like to add...I hope when you do pass your test you insure the E30 fully, as in, modified, because putting the Tech kit on it counts as a mod!
