I found a car locally that I'm interested in purchasing. The price is very good, but I'm a bit leary of the transmission issue. What would you all suggest as a process to check out what is going on as described below but the current owner. Thanks.

"very nice mercedes has every option, power seats rear and front, heated seats rear and front, pw,pd,cruise,sunroof,power telescopic steering,leather ,everything, interior is in mint condition. everthing works on it. has 190,000 runs and drives great, but the clutch between 1-2 is going bad, still shifts pretty good. the guys at the shop said it would cost 1200 to fix it but i can drive it like it is because it is going to take along time for it to go out. do not have the money to fix or i would."
