I am completely confused about the prices flying around in here, E30's are NOT worth anything like this money!?
Fact is, they are worth whatever people are willing to pay for them. There's about 950 odd Sports still registered in this country, the majority of them are going to be dogs. Good ones will get 5k +, but there are still the odd few that sell for less than what they could fetch. They usually sell from between £2000-5000 depending on condition. Sometimes more. I seem to recall one up for sale for near 10 grand late last year.
Many are tired now, diffs whine, gearbox's are slack. Engines tappety. Check to make sure it has all its orig spec. Its best to try and buy one that hasn't been messed around with to much, i.e horrible rear lights etc.
Rust is a major issue, rear arches, around the boot, under and around the front window, battery train. Also check in the boot where the battery sits and the other side. They can fill up with water and rust inside out. Because the sport came with the Mtech 2 kit, nearly 100% of them will be rusting underneath along the sills. Sunroofs also go. Some didnt come with sunroofs and came with aircon instead, though these are rare. Mud flaps are the devils work!
Engine wise, they are not to complicated. Check for obvious Head gasket signs, rather common. Coolant should be changed every couple of years, but most are not now. Can lead to damage. Make sure the oil light goes out quickly, as well as checking the obvious exhuast fumes. The M20 is a smooth whiry straight 6, you should be able to tell if it sounds wrong but also keep in mine the age of these things!
Performance wise, not bad. Supposed to make 170 odd BHP standard, but of course most probably wont by now. 0- 60 mid 8's. Some have been turned in to 2.7's like mine, 190bhp odd +.
Like someone has already said first you have to find one that's up for sale, and in good condition. Also check that it is a genuine sport, lots of fakes.
It should say sport on the V5, and they were ONLY ever 2 door and only a UK specification car. They all came de-chromed, had discs all round, Mtech sport suspension, Mtech steering wheel, Mtech spoiler front rear and side (styles 1 and 2 depending on age of the car) They had a 5 speed gearbox with slightly different ratios altering the 0-60. LSD with 25% lock up (I don't remember the life of these, but most have passed it- they only have a certain lock up life, and plenty have seen a lot of car park action). Black anthracite roof lining, check control system. Front fogs, headlight washers, and map reading lights.
There is more, thats just of my head.
