i have a pristine condition 2003 H1 wagon. i put a 3" suspension lift on it and bigger tires. upgraded certain components for strength and have a pioneer z2 in it for sound and sights.
i "gently" offroad it and its walks over stuff ive had trouble with in other vehicles.
they only made abt 4-500 units per year for civilians, so the H1's are considered rare and maybe even exotic.
as far as H1 vs viper....the h1 is much rarer and hence after initial depreciation will hold its value better than a viper. as far as gas mileage goes.....what viper u guys driving, cause my h1 gets better mpg...

. if i had to keep only 1 vehicle, in light of all things considered, id have to keep the H1.
i love both though....
