Rent the u-haul. the last thing you want is for the car to not even work and then you'd have to have it towed anyways. rent the u-haul, get it to your house and then try diagnosing and fixing the problems that you found, not what someone is telling you. then take it for a drive. at least that way, if anything happens, you'll be in the comfort of familiar turf and can easily have someone give you a jump or tow it x amount of miles instead of 2x amount of miles :-)
