I have always liked diesel power, but large diesel pickups are impractical for me so i figured id look into some mercedes diesel vehicles, i went and looked at a pretty clean 1985 300d turbodiesel this car ran and drove good but it seems like everything else on the car doesn't function so well, such as the power windows will not move up or down the locks dont work, the wipers, power seats (i think but forgot to check)and probably other minor things. the reason i went and looked at this car was because i was telling a buddy how a car like that would be cool to have and he realized there had been one sitting at his work for at least 4 years. so he told me to come look at it. if everything worked i'd probably buy it, yes i know its 25 years old and cant expect it to be like new. but i want to know if buying this car would be worth it. it had 164,000 miles if the odometer even worked and was pretty much rust free, and the owner wants $ 1,500 but he's open to offers, so i could probably get it cheaper. seeing my username im sure its obvious im into nissans, and nissans are pretty much the only vehicles i ever got into and they dont use vacuum for anything except some emissions and brake boosters. i want to expand my horizons though. if i picked up this car is it pretty easy to get all these vacuum powered accessories to work again and is this car worth the asking price????
