Tómatelo con calma, cariño

I saw this about 10 years ago ... but really like it. Here's what I remember of the movie:

A young man travels a long distance to buy an expensive sports car a few days before his wedding. His new car has problems and he is stranded. He trys to get the car fixed but finds out because he didn't buy an "extended warranty" there is no warranty on the car and he has bought a worthless lemon.

He sets out to get even with the dealership. Along the way he meets a beautiful woman. He tries to buy a bottle of Dom Perignon Champagne because she tells him it makes her wild. He gets robbed at the liquor store when trying to buy the champagne. The crooks also steal his champagne. Movie is very funny, strange, and entertaining.
