I'm not sure how resale value here plays much of a role. Unless I buy an older vehicle that's fully depreciated (e.g. old w123 or w126 mbz), I'm going to kill value anyway with all the miles I put on the car.
My jag was very reliable, the only major issues I had was a broken telescoping wheel and the passenger window motor, both easily fixed and under warranty. That said, thanks for the notes on the VW.
Diesel has been more expensive here mostly due to demand - it fuels more than just cars, it's used in industry, and thanks to the global economic boom we experienced, demand rose considerably. It doesn't QUITE make sense because diesel and gas come from effectively the same source..
I like the idea of the mbz coupes, I've looked into those before, but I'm hesitant to pick up a used car again. It was just too much of a love-hate for me.

Thanks for ya'll's help!
