I am 6'1" and drive an EZGO RXV. It does not slow down going up hills and has taken me all over TV for 3 years. I had the batteries replaced about 3 mo. ago under warranty (4 years). A friend has a Par Car and I think it has a bit more leg room, but he is getting new batteries after 3 years and his warranty was 18 mos. so he has to pay.
