I must say today's experience has been great... i have been getting my truck smog checked here…read moresince they opened. Every time has been great, but this time my truck was leaking oil. They were able to help me with my smog check and let me know what was wrong with my truck all the way around. I needed an oil change and they took care of it no problem. Also was able to tell me which tire pressure sensor was bad and was able to tell me about my stability track. On top of all of that they topped off all my oil and fluids. Check all of my filters. It was just a really good experience that I haven't had from a repair shop in a very long time not even the dealer does it like that anymore. I really appreciate how transparent they are. Five stars really aren't enough stars for them. And the best part is, it's a price you can't resist. Thank you guys!
