We were loathe to feature yet another Cadillac for the Deal of the Week, but in light of the SRT-8's expiration and also in light of the Cadillac CTS-V's worthiness as a V8-powered performance machine, we'll go with that. [Thanks Joe.] With a new high-po entry Caddy not scheduled until next year โ€” a car Bob Lutz says will suck the doors off an M5 โ€” it's a good time to take advantage of a clearance offer on this year's model. It's the 2007 CTS-V, a car that combines a decent platform with the GM's proven LS2 V8 producing 400 horsepower. It's already a good power-to-dollar value at fifty grand. At under fifty, it's a bargain. That's $4,000 cash back or limited interest-free financing. It's like a bargain-basement BMW M3 with secret cred. And when you're out cruising, you can wear either a porkpie hat or gold chains. There's no need to go with both. [Cadillac]
