Thanks for all the support
I think I'm a little bitter, because I've already spent over $500 looking for a car and haven't found the right one yet, not to mention all the time. It's like a full time job!
I think I won't buy a car that does not have full service history, and I will review it myself before making any decisions.
Just today, I called a Nissan dealer who has a 1992 500SEL for sale for about $11,000, who said the mileage on the car was approx. 63,000 miles. The car is black on black and shows well.
After a call to Mercedes Benz, I discovered that the car was serviced in May 1988 and had 117,000 miles. I'm getting sick and tired of these people trying to screw me.
