1997 Express 1500 Conversion w/55K miles in Mar 2002. 5L V8 equipped. Reliable for appx 30K miles, then all heck broke loose. By 105K miles: Trans replacement (NO tow pkg), rear axle seals, both u-joints, fuel pump module, gas gauge sender, starter, alternator, radiator repair, A/C repair, 2 fuel injectors. Upper intake manfifold gasket. Chronic Intake Manifold coolant leaks, Vacuum line leaks, tail-lite replacement. #8 cyl ate spark plugs (every 3K-5K miles after 80K miles) finally suffered ring or valve failure at 105K (0 compression at idle). RH side rear door hinges corroded and upper hinge broke making door unuseable. Prior to engine fail - spent over 8K on repairs in 10K miles.
Nice body design, conversion gave roomy interior/comfort.
MAJOR reliability issues. Oil/grease fittings for hinged doors needed. Underpowered with 200hp 5L. Worst experience with any car I ever owned.
