I came in to get my 1995 Tacoma fixed. They said as advertised it wouldn't be a long wait/time…read more They had me waiting for over an hour while servicing two other vehicles who showed up later than me. I guess since I'm not a regular or a friend, I was treated differently They were hung up on trying to see what other issues without running the smog. I don't know what the hold up was or if they were unfamiliar with the truck. Or if I was bothering them But after all that, they ended up failing the truck and also charging 80 dollars. Surprising since other smog shops won't charge you if you fail. The only highlight was the female technician took the time to explain the results. The others seemed sarcastic/annoyed and more interested in my truck and seeing if I'll sell rather than helping me with the situation.

This is the first 5 star review that I have ever written for anybody. I must let readers know about my positive experience with Top Smog. I had trouble finding the place but called the shop and got politely and quickly redirected. Next, I was going to hang outside in the heat while my car was getting the smog check until the owner noticed me and pointed towards a door where I found a air conditioned waiting room complete with TV. Finally my car was done 20 minutes later and was charged only $35.00! WOW!! So give yourself a break and give them a try. Thank you again Top Smog and I'll be seeing you again. read more
