Chevy's big 2-door coupe gets a host of detail changes for 2007, including four new paint colors (including an extra-cost Red Jewel Tintcoat) and a tire-pressure-monitoring system. The LTZ model has been discontinued, leaving LS, LT, and SS trim levels. Monte Carlo LT models get additional standard equipment including 17-inch alloy wheels, while SS models get standard XM Satellite Radio and an optional Rally Stripe package. The 3.9-liter V-6 has been dropped, leaving the 3.5 V-6 and 5.3 V-8 as the only engine choices; the V-6 is available in an E85-compatible FlexFuel version.
