My 98 Volvo failed a smog test and lo and behold, Ackerman's was right next door to the smog test place and had good reviews. Plus side, they sussed out that it was vacuum hose issues AND as an added bonus, they took the initiative to take my car next door to have it re-smogged,,(passed) so when i showed up not only were repairs done, I didnt have to go next door and wait for my test. Oh and they assesed my Cat. Converter However, I was dissappointed with 2 things. First, Bruce told me he thought i needed new spark plugs, which i just replaced 2 months ago. Especially troubling because i had told him when i brough the car in the plugs were new. I assume this was an error and not an attempt to.upsell me., still it didnt sit right. Also the free inspection is a 15 minute once over. Dont bother. Still worth a four because of going the extra mile to get the old beast smogged.
