IIRC you have to remove the trim pieces above the doors (and buy replacement clips) and then use silicon to seal up the area.
Any clarification from the seller about the VIN yet?
EDIT: I decoded the check digit based off of
this link and it is indeed supposed to be 1. So the correct VIN# for this car is JHMZE1371YT000007. Carfax indicates no available records for this VIN#.
