This 1998 GMC Sonoma SLS, finished in Pewter Metallic with a beige interior, features a potent 4.3-liter V6, 16-inch wheels, sport suspension, bucket seats, and air conditioning. It includes tasteful upgrades like a Dynomax VT muffler, a hard-shell tonneau cover, and a BOSS head unit, and comes with a clean, accident-free Carfax report. The truck shows some exterior blemishes, interior wear, a dashboard crack, and rust on underbody components, with the seller noting an intermittently working rearview camera, oil seepage, and a rough idle with "piston slap" on cold starts.
