You didn't say where you were located, so I checked your profile and no mention either, but it does show you have a 1991 (or was it 1990?) BMW 325ic. So you obviously have experience with older model cars, thus a 300 certainly sounds reasonable. Was curious whether you were looking to buy from a private seller or dealer/used car lot? I mention this because I'd like to see from either seller alot of maintenance and repair receipts. If they can't produce them, then I'm not interested. Or if you really like the car, find a good indy to evaluate it for you. As you can tell from this forum, there are alot of people committed to maintaining their Benzs and from time to time they do sell them. Try to find yourself such an individual or a salesperson at a dealer that has clients that have older model Benzs for sale. Good luck.
