1990 300e 247K miles, Well, in the past year I have replaced my bower moter and blower motor regulator, ignition switch, all brakes and two new rotors. Last year new tires. Within the past four years: a MB shop rebuild of the top end, new radiator and water pump and A/C upgrade. Uses no oil. Now the rear sounds like it is beginning to whine. I think I'm at the point to ask "what is it worth"? The thing drives and still looks good, wanted to try to get to 300K but .... besides, the wife is having a hissy!! Any clues to what I should ask for it?
