Pontiac Solstice GXP – Review: Pontiac wasted no time making early adopters who bought a Solstice over sticker feel like they got ripped off. The new Pontiac Solstice GXP is the car they should've pined for, the car they should've waited for, the car they should've paid over sticker for. It's got the same great styling but includes a few refinement tweaks and a sweet new turbocharged engine that delivers the performance promised by the Pontiac's design. It's a flawed beauty to be sure, but like that crazy girlfriend in college, its fun factor trumps its personality quirks – for a little while, anyway.
