Diamond Bar Mobil

I have been here twice and both times were a very pleasant experience. This is officially my go-to now for car repair needs. They are so friendly, helpful, thorough, professional and last but not least, honest. As a female, I had been taken advantage of by so many car repair places. But here it is different. So glad DB has this car shop. It is a gem. 2 thumbs up 💯 I recommend.

Great service! Great gentleman! Nick was so understanding and even stayed open longer to help me out. I’ve been a returning customer and I will continue to come back.

Don’t. Just don’t go there. There bunch of other professional shop out there. Just don’t. Believe me. Your life will be much easier if you walk away and stay away from those people. Over-priced, Not professional at all. They will keep you wait and waste alot of your Time and tell you come back tomorrow and still do nothing for you even they not busy.

For the past 5 years they have had the highest prices of gas I have ever seen in LA county…trashy

We were quoted a minimum of $139.00 for a Smog Check plus additional fees for our vehicle, which is older than 1999. The explanation given was that older vehicles require more “work” and needed time for their machine to calibrate and that we should come back another day. However, we noticed that the posted RV rate on the wall started at $139 with normal vehicles starting at $89 - basically tried to rip us off on our Honda! This discrepancy in pricing was concerning, especially since we've never paid over $100 for a Smog Check elsewhere. Recommend potential customers to be cautious and verify pricing details before proceeding with this business.
