Comparing reliability and maintenance cost for H1 vs H3

[HummerJim]

H3 is an order of magnitude more reliable and the maintenance costs for the H1 could easily exceed the purchase price of the H3. The heater core is almost impossible to repair set aside $3700 to change it over to the new style. Then there's the tire inflation system, figure another $3000 to fix that if your problem is a minor one. If you want one where you can do more yourself look at a 1996 gasser, not much power but easier to work on.
