2003 Chevrolet Silverado 1500 2dr Regular Cab LS 4WD SB (4.3L 6cyl 5M)
Have had this 2003 Z71 2-dr since new. It currently has 134,000 miles. No complaints about reliability with just basic maintenance. Original tires only lasted about 40,000 miles. Replacements have lasted about 80,000 so far. Only parts that have broken on me are two rear U-joints,water pump seal seeps, and the battery died after 7 years. Clunking noise from steering column is a little annoying, but apparently common for this model. Under-body rust is a problem even though I regularly wash the underside of the truck. 4x4 system has been rock solid in snow, ice, mud, you name it. Tows/hauls with no problems although trailer brakes highly recommended for heavy loads/high speeds.
4x4 system, 5.3 LS style V-8, reliability, cost of ownership relatively low for a full size pickup.
Put on better tires, electronics become unreliable after several years (gauges, radio, CD player, turn signals), and under-body should have been coated/treated better from the factory. This, after all, is a pickup and just might be used more places than city streets(sand, rock, etc take a toll).
