ive got the 3 as you know, but ive seen plenty of H2's go through the carwash i take my too down here in FL. However as for the parking space thing youll realize rear visibilty blows, and on the H2 im sure its worse, best advice i have for you is PARK BACKWARDS, its way easier to back in with a hummer than try to back out with a hummer, and as a plus your car looks better in the parking lot
