hahah what a coincidence, i went and checked out this very E30 last year when it was first up for sale......I offered him 950,000 and left, when i got back to him the next day he said he had sold it off for 975,000. So its still up for sale. At that moment I was cursing for missing out, because from all the E30's I've come across this one is in great condition, particularly the body. one mill is indeed a bit steep, but I think this particular car is worth it, and to be on the safe side as Rukster said better check it out with the specialist at Kelaniya, the car has been serviced there as well.
If I remember correctly, the replacement exhaust looked like a non-original item, and the vibration is probably due to a missing wheel weight or a worn steering joint. When I drove it everything else seemed ok.
Stuff like the door locks problems are expected, particularly with SL conditions and a car of that age. My E30's central locking has also gone haywire at the moment, and my headlight wipers don't work either
