What is good about a camaro?
Is it better than an '02 mustang? You should have added some information - like if the 96 you're looking at is a 6 or an 8 cylinder, and whether your brother's is a stock 6 or 8.
6 versus 6, or 8 versus 8, I'd lean toward the Camaro. Styling-wise I give the edge to the Camaro. Interior, I would have to give the mustang the nod in terms of comfort and visibility. Both have ugly gauge clusters, so that's a tie. Girl factor - I give them both a tie as well; the Mustang looks like a girly car, and sadly I get more compliments from the ladies on my Grand Am than my Camaro!
Performance modification - again I'd say 'tie'; the LT1 has a limited market for performance mods versus the modular 'stang engine, so cost/vs/performance is about the same. The 6's seem to have slightly more mustang support than GM.
As for that previous post? Get a Honda? Why on earth would you want to offer a bag a pretzels to a man who asked for steak?
