in my '99 Cavalac. My Cavalier was valued at less than a thousand bucks several years ago before it got caught in a major hail storm. Considering that it's not worth much, I use it to learn how to work on cars. Tonight I charged the A/C and I'm getting cold air for the first time in a while. Not a huge thing but as a backup vehicle, it sure is nice to ride in comfort if not in style. I got my Johnsen's R134A kit at Fred's Dollar Store nearly ten dollars cheaper than A/C Pro. I had never heard of the brand but read good reviews.
