In regard to TxBill comment about power....the 1992 300SD is my third diesel benz the first being a 1985 300SD and then a 1992 300D 2.5...I can say the 1992 SD is much faster and smoother than the 1985 and a little slower than the 300D ,which was a rocket for a diesel. but also in regard to the other issues closing assist and evaporator...I have had both done in the last year(warranty)...Having owned 126 and 124 I can tell you the 140 shines above those two...but the repairs are very expensive....I mentioned to my tech at the dealer I wonder what will happen when the cars are worth 8-10K and the repairs are about as much as the car is worth?....
