That is, I think you want the dealer to give the best price on the car you want, not to get a car for the lowest price. Presumably you're going to have it for a while, and presumably you can afford either. You want to pick the car that fits your needs best. Don't let them decide what car they want to sell you. If you try to bargain with them on price between 2 different cars, you lose sight of the real goal.

A friend at work has a 2004 Corolla. He's about 5'10", maybe 150 pounds. It's a pretty decent car and fits him pretty well, but I don't think that someone as tall as you would be happy with it for very long. It's rather tall and narrow compared to the previous models. The Camry would fit you much better. It would be a much better car for a growing child too.

Ditto on Peter and Barry's comments. You're going to be sitting in whatever car you get for a significant fraction of the next few years. It should be comfortable for you.

Cheers,
Scott.
