This robust 1994 GMC Suburban K2500 SLE, having traversed just 36 kilometers since new in Gibsonia, Pennsylvania, is a formidable example of American trucking. Originally used for traffic control duties by Pennsylvania fire companies, this turbodiesel-powered four-by-four boasts a 6.5-liter Detroit V8 and a four-speed automatic transmission with dual-range capabilities. Finished in an assertive white over green color scheme that contrasts nicely with the gray cloth interior, it's ready to tackle any demanding task while seated comfortably on its high ground clearance.
