Since I can't convince my just turned 16 son that a 240D is the right car for him, he has been considering a 190D or a 190E. I really don't know anything about these as the 123 and 126 diesels are the models I like. What are the good and bad points of the 190 series? From what little I know I would lean towards a diesel with a stickshift or the 4 cylinder with a stickshift (if there is such a thing). Priorities are reliability, mileage, ease of service, and parts availability. Any advice such as what years, engines, etc are most desireable would be appreciated. Thanks
