Impala/Grand Marquis/Grand-Prix/Bonneville reliability?

Most transmissions are all designed about the same. As far as the cars go, their all not bad choices. But the crown vic is rear wheel drive, the others are all front wheel drive, which will do better in the show. With any car you buy, its best to let a mechanic take a look at it, unfortunately 9 out of 10 times no one gets rid of a "good running" car. And if you find a car somewhere that sounds to good to be true, most times it is. Avoid used car lots, as you will pay top dollar for something, and if you have a problem, you spent all your money. Most transmissions have a life expectancy of somewhere between 80 to 115k miles. Just in their design, I see it all day long. So have someone look it over good before you buy. I always recommend a used car from a new car dealer. They have a reputation to protect, and will send junk to the auction block for the used car dealers to buy and sell, new car dealers make money off quality pre owned vehicles, hope that helps ya,.,.
