I know that these cars are very complicated and can become nightmarish money pits. I have an opportunity to buy a 1995 S500 gun metal gray on gray with 83Kon the odometer. The seller is asking $11,000.00. I know what to look for in these cars, but I'd like some advice on the price. If I offered the seller $8,200.00 or less would this seem to be a reasonable starting point? What do you think?
