the 300d. because that is what i am most familiar with. the 280 engine is also bulletproof mechanically but the fuel injection is prob not as reliable as the diesel. but either car if it runs and shifts well will prob give good service. if you are in the rust belt the 300 will be somewhat less rust prone. the 450 i wouldnt want. 971k ????? really? amazing, but why would they lie about that?
