The 2007 Chevrolet Monte Carlo comes in three trim levels: LS and LT are powered by a 211-hp 3.5-liter V6. The top-performance SS comes with a 303-hp 5.3-liter V8. All come with a four-speed automatic transmission. (The 3.9-liter V6 offered for 2006 is no longer available.)

The Monte Carlo LS ($21,015) comes with air conditioning; cruise control; power windows, mirrors, and programmable door locks; six-speaker AM/FM/CD/MP3 stereo with speed-sensing volume and auxiliary digital media jack; front bucket seats and floor console; six-way power driver's seat with manual lumbar adjustment; split-folding rear seat; tilt steering; metallic interior trim; automatic headlamps; 225/60 all-season radials on 16-inch steel wheels; 7.0 Generation OnStar with a one-year subscription; and a Passlock security system. A recent upgrade to the standard remote keyless entry allows drivers to use the red panic button to locate a car misplaced in Lowe's vast lot without activating the alarm. ABS with traction control is available ($600); as are 16-inch aluminum wheels ($350) and carpeted floor mats ($80).

The Monte Carlo LT ($22,625) adds dual-zone automatic climate control; Radio Data System (RDS); leather-wrapped steering wheel with audio controls; carpeted floor mats; ABS with traction control and Electronic Brake-force Distribution (EBD); a tire-pressure monitor; and 225/55 touring tires on 17-inch machined aluminum wheels. Powertrain dampening is upgraded for quieter running. LT is available with more options, too, including a power tilt-and-slide sunroof ($900); leather seats ($795); six-disc CD changer ($295); XM Satellite Radio ($199); eight-speaker premium sound system ($250); and universal remote ($100).

The Monte Carlo SS ($27,740) comes with leather upholstery, heated front seats, XM Satellite Radio (with a three-month trial subscription); and 235/50 W-rated Goodyear Eagle RS-A tires on 18-inch machined aluminum wheels. Also standard is a stiffer suspension that GM calls FE4. A Convenience Package ($240) for SS adds a universal remote, auto-dimming inside rearview mirror, and heated exterior mirrors. Also available are polished aluminum wheels ($350) and a new Rally Stripe package ($395) in black or silver. Cloth upholstery can be substituted for credit. Otherwise SS offers the same options as LT.

Optional on all Monte Carlos are an engine block heater ($50); remote starter preparation ($30); and seat-mounted side-impact airbags ($350). New last year, the dual seat-mounted bags replaced a single door-mounted bag on the driver's side only, and help optimize head and torso protection for the driver and front passenger.

Dual-stage frontal airbags are standard on all models, as are front seat belt pretensioners, three-point seat belts in all seating positions, LATCH child-seat anchors in all rear-seat positions, strategically padded interior roof rails, and a strengthened front seat structure.
