They could have easily sold me on replacing my timing chain, gears and all the parts that it takes to rebuild that area but instead I was advised that it would be best to have the transmission checked out first before spending $2500 to $3000 with them. The car is only worth about $5000 so it wouldn't be worth spending all that money on it to then have the transmission break down on me and I would have to spend another 4-5K. Thank you for honesty!

I only have had one problem and it was a bad gas cap. Timm used a cap he had, told me I had to replace mine, and my car passed with flying colors. His price is reasonable and I am usually in and out of his shop in under 30 minutes. My only complaint is that he is a SF FOURTY NINERS fan. Being a RABID & DIEHARD GREEN BAY PACKER fan, you can see the problem! Thank you Timm for taking care of my car for the last 20 years.

I planned to run an errand and head straight over, unfortunately I left my paperwork at home. Not knowing they could do the testing without it, I ran home and realizing it was already time for my appt, I called to let them know I was running late. Thankfully, the next appt was already there, so we were able to basically switch spots (them taking the current time that had been mine and me taking theirs). The woman in the office was so helpful and kind about it! I got there before the updated appt time while the vehicle before me was finishing up testing, and we were in and out like a flash after that! Very friendly, fast flexible service, and great pricing. All in all, as painless an experience as smog checks can be, would recommend!
