Just came across a legitimate good buy on my FB:
1992 BMW 325IS Coupe for sale
Obviously, I know the seller in person, and have casually seen this car in person as well (but I never paid too much attention to it since he has some far more interesting cars to look at). I can vouch for him being a very meticulous car guy -- to the point of being OCD, and he always takes care of his cars. This one didn't receive as much attention as his other cars, but knowing him, there wouldn't be any known reliability issues at all. But as the ad says, it is a 25 year old car. Problems are bound to come up when the next owner starts driving the car.
The ad says the price is firm, and I can almost guarantee you that his price will be firm. Looking at various ads on CL, I think his asking price is fair.
Hopefully someone that appreciates this car will pick it up.
