The Caddilac CTS (and the CTS-V) is an intriguing car. I find it beyond ugly, but you can get the honking fast GM 5.7 liter V8 package and a manual transmission. Likewise, you can get the far less ugly Pontiac GTO. It may not have the attitude of the old GTO, but taken by itself it's probably the nicest Pontiac in decades. The other intriguing American car just around the corner is the next-generation Ford Mustang. Ford claims it's going to be based on a more modern platform, so there's at least some chance that it will be good for more than just drag racing.
