"Looked at the inside of my car, saw a roll cage and said out loud "Oh No". Didn't know how the get into the engine bay, looked at my catalytic converter for a second then says I don't want to deal with this and hands me back my keys. I have a 100% street legal catalytic converter that was on my car last year when I last got it tested. Lazy smog shop owner. Said he wouldn't smog it for $80, that tells me this lazy owner shouldn't have his smog license! ⚠️⚠️⚠️⚠️⚠️⚠️ GO SOMEWHERE ELSE. YOU'VE BEEN WARNED! ⚠️ ⚠️ ⚠️ ⚠️ ⚠️ ⚠️"

"This gentleman did a outstanding job. I was the victim of one more catalytic converter theft, after it was replaced he made he made sure that it was a California approved catalytic converter in order to keep me from having trouble later, in case the shop that installed it put in one of the 49th state catalytic converters that are not legal in California"

"I paid 40 bucks he told me that my car had to run. But when I went back he said he would need 40 more and every time. So I decided to let go of my $40 and went to a different shop the shop did smog test and once it passed they asked for $45 one time fee which was great."
