When my job had me traveling to Dallas twice a month, I got to know the guy who ran the airport Avis. I'd give him a heads up whenever I was coming and he'd fix me up with a Camaro or a Mustang or a Challenger or a Charger. I liked them all, but the hemi V8 Dodges were my favorites.
I do love V8s, but I ended up buying a V6 Challenger as a daily commuter, and while it's not quite as quick as the V8 version I think it handles a bit better; the heavier engines tend to create a bit of understeer. And even that little V6 is plenty quick. When I was doing a 40-mile one way commute, I wanted the better fuel economy. When I stopped doing that long drive, I put on wider rims with a set of Mickey Thompsons and now it corners like it's on a rail.
The key that's made all these cars better than their predecessors is the electronic transmission. Having 8 speeds lets the engine stay near max HP when accelerating.
