Bob & Sons Auto Repair at 657 West Grant Highway, Marengo, Illinois.

Spent over $200 (in cash) at this place to fix my car. My car was never fixed. In fact, the complete opposite. Bob actually lit my car's engine on fire and caused severe damage that is now going to cost me a lot of money. There is a reason his services are cheap and he makes you pay him in cash because not only does he not know what he is doing- he also claims to do something when he didn't actually do it.

Save yourself the money and the headache, take your car to an actual auto repair shop that let's you pay with a credit card because that keeps them more honest and more hesitant to damage your car. It's not worth taking the risk with a local shop like this. By the way, when I went to pick my car up he left the key in the ignition completely unlocked outside... I was told the key would be put under the mat. Avoid this place, you have been warned.

Edit: my car has been fixed by a different auto repair shop and no surprise they told me Bob never actually even changed the PCV valve. He never even took apart what he was supposed to take apart to reach the PCV valve. He took the cash, throw the brand new PCV valve we gave him to install, and said he did it.
