This was my first dodge. I bought it off a guy who put 130,000 miles on it. He drove on the highway to get to work every day, and he dropped the fluids religiously. The only issue I've had with this beast is that I had to replace the water pump (expected for mileage). Since I've got it, I've abused and pushed it past its limit, and it doesn't stutter. You tell it to do something, it'll go. Handles like a car.
5 speed manual. Gives you more control, especially when towing trailers down hills.
Gas mileage for a v6 stinks in the city, A/C does not seem to be a factor. I've gotten 21.5 on the highway though.
