Hi everybody, new to this forum allthough i have had many mercedes in the past mostly 1970's models, question is i have just bought a 1992 190 diesel non turbo, and the car is very near to immaculate, when i came to drive off i was supprised how gutless it is, i had intended to tow a small caravan with it but i dont think it will pull it. i can't try it as there is no tow bar on. it seems a shame but other than put a bigger engine in it will be no good to me. would a 2.5 engine go in it, thanks
