I purchased my black beauty, SLS crew with 50 miles on it. I never had a moments problem with it, until I moved to California. The gas destroyed my engine. From 25 hwy/18.5 city to 14.5 hwy/12.5 city. In 9 months. The roads are so crappy they shook the speakers off their mounts and the asphalt ripped up my tires. They were pristine at 15,000 and needed replacing when I traded it in at 25,000 in 2006. It broke my heart to let it go but I couldn't afford whatever would happen next. Sparkplugs, EPA accessories, hoses, and belts were all replaced at 23,000, but the MPG didn't recover. WARNING!! Don't bring a midwest vehicle to California, sell it and buy one made for out here.
