Auto inspection service near Monrovia, CA

Today 8/8/2015 I took my truck to SmogZone at 12365 it was about 3:45PM, they closed at 4:00PM. I was greeted by John Yang who speaks limited English. In short he ran a SMOG Test on my truck, he never brought it into the bay to run any RPM tests. At 4PM he tells me "Oh your truck didn't pass." On the form he points to Smoke Check. He said "I do not know what that is, you must go to a SMOG Certification to have it checked, I'll charge you $35 to retest in 30 days." I was so upset, the truck has 36,000 miles, not a hint of smoke. I came home and looked up Smoke Check and found he is the one who enters Smoke Check. I plan to dispute the $49.75 he charged me. I should have known based on their previous bad reviews not to go there.

First clue, ripped off, the bad about a 22 year old after a 31 year seasoned businessperson. Ray

My wife’s expedition blew a heater hose while at Coffee Bean with steam coming out from under the hood she drove next door to American Tire. The guys “T” as in Mr. T was very helpful, even assisting her a tow to the dealer through AAA (garages don’t typically assist you going elsewhere, but they were helpful). Upon arriving to assess the problem I realized the “new” heater hoses are not hoses at all but rather multisegment manifolds. I felt comfortable with everything explained, they confirmed that the parts were available and it would be done by the end of day and it was. Very happy with the service and how we were treated. 5 star all the way!

Took my car there to have smogged today...they failed me and told me that I would have to pay $175.00 to have my vehicle repaired to get it to pass...I said no and went to another station where my car passed smog no problem.. Never again!!!

I would have to say that they are the best at what they do. I took my car wrecked from the accident. They towed my car for free to their shop and started on the paperwork right away. Not only they are honest, they are also reliable. In only 3 weeks I had my car back, in perfect condition. A+ to Pristine Auto. God forbid I have another accident, Pristine is my body shop!

Great service honest & clean environment.20 min. test.

Great place. Mike (the technician) tested my car and had the paperwork ready in less than 15 min.

Freddie was a great help and very respectful. I had a flat and it was closing time and he got my tire fixed right in time super fast so I can get back on the road. A plus service. Richard Ryan

Very Good Serviced!!!

My sons Mustang was in our garage seems like forever we tried to get it towed to a shop but they wouldnt send a flat bed tow truck even when we request one about 3xs so my husband decided to put the fuel pump in himself while at the Auto Zone my husband met Ali and Ali gave him some advice and his ph# and said that he was mobile.We then decided to have Ali put the pump in. You can tell he KNOWS what he's doing/talking about.Ali had the fuel pump in it didn't take him long at all. And the price was GREAT!! From now on Ali will be our Mechanic and no one else!! THANK YOU ALI!!!
