The first of four is the Lucerne CX, which at $25,990 is pretty packed in most ways - power everything, ABS and all-speed traction control, six air bags, etc. - but lacks minor things like dual-zone air conditioning, auto-dimming rearview mirror, MP3 playback, leather steering wheel, universal remote, lighted vanity mirrors, and power seat; it's also the only one with cloth seats.
$2,000 more buys the $27,990 CXL to fill in those blanks while upgrading to 17-inch wheels and the "Ride and Handling" suspension. Another $2,000 buys the $29,990 CXL V8 with the Northstar engine, which includes the "sport" suspension, dual exhaust, magnetic steering with a faster ratio, and a rearview mirror-embedded compass.
The final $5,000 buys the V8-only CXS, way up at $34,990. It gets memory settings for the seat, mirrors, audio, and climate controls, heated seats, a sport steering wheel, side mirror turn signals, 18-inch wheels, Magnetic Ride Control, and StabiliTrak stability control.
