I have been going to John's for over 3 years. Prior to moving to Boulder, my mechanic was my brother's best friend, so I was used to excellent, honest service. I first went to John's when I popped the oil pan of my Jetta. I went to a quick-lube place who alerted me of the problem & told me that it would cost about $700. A friend referred me to John's, who quoted me $400. Needless to say, I went to John's and have been going ever since. They let me know what my car needs done now, and what can wait. They have never charged me more than estimated, and have quickly fixed anything that I had issue with. I am a satisfied customer!
