In 2007, the GMC Yukon received badly-needed interior improvements – improvements that were lauded by many auto industry folks. It stands to reason, then, that the 2008 GMC Yukon remains virtually the same as last year’s version. Available in SLE and SLT trim levels, with your choice of two or four wheel drive, the Yukon features four doors and seating capacity for up to five passengers. The standard engine is a 295 horsepower 4.8-liter gas-powered V8 with a 4-speed overdrive-enabled automatic transmission. The Yukon comes equipped with plenty of amenities.
