babtahi,
surely enough it seems that the body shop did more than just 'body repair'. I've been in this situation a couple of times and it makes me really really mad. And at times I've gone back and yelled at the shop as well. but as we all know, they totally deny that they even touched anything but the body panels etc. So no use doing that. Given your car is a 96 and probably out of warrranty, I would still suggest that you take it to the dealer just for a checkup and have them figure out exactly what's going on. And if the body work you had done was part of an insurance claim then you can have the dealer bill with the repairs attached to the total claim since it was partly the body shop's doing.
good luck.
