WHICH OF THIS IS BETTER TO BUY AND WHY? CHRYSLER CONCORDE 96 V6 120000 MILES OR FORD THUNDERBIRD V6 96 100000 MILES?

I would buy the concorde IMO.

I have a '96 Concorde Lxi. It's been the most reliable car I've ever owned. It currently has 153,000 miles on it. The only major thing I ever had to do with it is replace the intake manifold gaskets. A common problem with the 3.5. You'll know when you need them when the car starts idling very rough - it's sucking air, and the system can't adjust for it.

A few years ago I removed the restrictor from the air cleaner tube (same results you get with the EXPENSIVE after-market so-called "cold air" induction systems), and gained what feels like 25 or more horsepower at wide open throttle. Great fun. It'll easily smoke the tires from a standing start if I snap the throttle open. With that restrictor gone, it also produces a menacing 'howl' at WOT.
