These guys are awesome! I have an 11year old car. It was weezing and coughing, air conditioning not working too well. I needed an oil change and just a diagnostic to see if I needed to fix anything else. I decided to take it to Auto Surgeon in Roseville because it's near my home. Omgosh! Got the car back with the oil change and diagnostic done. It did not break the bank. Very reasonable. Got into the car and turned the key. I could not believe what a difference. it didn't rattle anymore, smooth engine, and the air conditioning was working better than ever. Really, really happy with this place. I will always bring my car back here. Thank you Auto Surgeon.
