Diamond Bar Mobil

"I went to Diamond Bar Mobile to have just one 'USED TIRE" mounted and balanced, and I couldn't believe the price they charged: a whopping $46.50! That's highway robbery for a single-tire service. The staff seemed more interested in squeezing every penny out of me than providing decent customer service. Adding insult to injury, their disrespectful attitude left much to be desired. Take my advice and steer clear of Diamond Bar Mobile Don't fall victim to their price gouging and appalling behavior. You deserve better service elsewhere."

"The price and service is as most people write about the smog check. I can't complain about anything. I left my car there before 4pm on a busy Friday, and then crossed the street to buy some groceries. It was ready in less than half an hour before I returned. The only minor inconvenience was the technician who did the smog check. He seemed friendly when I spoke to him on the phone but was aloof and impersonal when I arrived. He didn't seem to want to communicate. Perhaps he had a bad day. Other than that, I highly recommend this place."

"Came in for smog check. Excellent staff and services. Took 15 minutes and they sent electronically the certificate to DMV. Highly recommend!"

"Great place to take your car for maintenance, repair, tires or smog test. It's a smaller shop so its best to go early as they can get full. They are a STAR smog test station if your smog test requires it. Fuel isn't the cheapest but is reasonable for the area. Convenience store if you need drinks or snacks."

"I have a 30ft Class C with a bike rack and 4 bikes hanging off the back. This site is busy with a line of vehicles ready in the queue. My usual smog guy is out in Jurupa Valley with plenty of space to turn, but I wasn't about to drive in the crazy traffic with crazy gas prices. I understand folks complaining about prices, but heck, everything has gone up. I called at 11:15am and asked if they would smog my RV. In my head I was prepared that they would say no because I looked at the google satellite images of the place (still packed) and drove by earlier that morning and saw a row of security patrol cars ready for smog check. I was dreading the drive to and from in traffic back to DB. To my surprise they said they can take me. They cautioned me that they need to move cars to get the RV around the back and they would get it done by end of the day at 6pm. I was like, okay I'll bring by around noon. I pull up at one of the gas stations, walk in and they immediately started paperwork, no sitting around like my usual smog guy, took my info and keys. I was curious how, but I didn't care. I was free from the drive from hell. Sure enough, I parked in a parking lot next door around 5:30 to check them out from a distance. The RV was at the back where a ton of cars were blocking the way. He finished right at 5:57pm and I walked up as soon as he moved the RV to the front. The price was $149 OTD but worth it from a gas and sanity perspective. They were all accommodating and service was immediate (no waiting around for the customer except for the RV to move). There aren't too many places where an RV can pull up in DB, so this is the place for me."
