If the 2007 Cadillac Escalade EXT looks vaguely familiar, that shouldn’t come as much of a surprise, given that it’s based on the Chevrolet Avalanche. And, really, no amount of chrome or badging will disguise that unusual C-pillar.

So, under the skin there’s the backbone of a Chevy, but the Caddy does offer a significant boost in luxury and style, not to mention 403 horsepower from its 6.2-liter V8 engine, which, by the way, is exclusive to the Cadillac (the GMC Yukon XL Denali has a 6.2-liter motor, but it’s only good for 380 horses). Another feature found on the Escalade line, including the EXT pickup, is an all-wheel-drive system; Chevy and GMC versions are available with either rear- or four-wheel-drive.
