Superformance is excellent. I've been a customer since my 1996 Camry, and the service is excellent. Their customer rapport is excellent. If you can find an honest mechanic, you are ahead of the game. Tom and Johnny are really good people. One thing I really like, is that after an oil change, when I drive off, it doesn't smell like oil. I've had axles, and boots replaced, and a lot of other stuff. I really like their service.
