I concur--stay away from WalMart on this car. First they have probably never seen one, and have no idea where to do things. A co-worker made the mistake of going there (w/ a truck) and the guy did not even put the cap back on the oil cover--and he figured it out when oil started leaking out of the hood. Steer clear of the old WalMart...
A $100 bill is worth the peace of mind in my opinion.
