I did consider keeping R-12. Yes- R-12 cools better, but from what I understand is much more expensive, harder to source every year that passes, and very bad for the environment. Didn't want to take a chance if the there are more leaks to come. We just need it cold in the car, not very cold. The existing system was completely empty of R-12. The retofit kit/valves was only about $20 I believe
