Times are tuff for everyone (Covid), the owner and employees have always put forth a valiant effort to ensure that my vehicle can stay on the road safely, even though I make it difficult by owning a vehicle with more than 250,000 hard miles.
So for the years of great service and professionalism I thank you.

Chris was great with my sister this morning. Pep boys told us $1300 for new radiator, thermostat, and something else. Went to these guys and all that was needed was a radiator cap and it solved all the issues the car was having. I like these guys, they are down to earth and saved my sister around $1100. (They didn’t just add the cap for those who can do math.)

I cannot speak more highly of these guys. They’re straightforward, honest, and professional. They won’t beat around what’s wrong or try to sell you a part or service you *maybe could* need. They’ll tell you what the problem is, tell you what you need to keep an eye on, and what needs to be done immediately. They’re good, trustworthy people. Be aware that this causes them to be busy! You probably won’t get a same day oil change. Call ahead and make a plan. They’ll quote you a reasonable time frame and work hard to get whatever you need done as quickly as possible. I won’t take either

I've been taking several of my vehicles here for years, and have always been taken good care of. I appreciate the honest nature and patience Casman's employees have always given me in explaining what my car needs.
Further, they have always been accurate in their time estimates to return my car fixed, which is very important to me as I too run a small business.
I love supporting local guys who care!

Beware! do not take your car to Casman's. they charged me $300 to fix my AC. less then one month later the AC is not working again. i take the car back and casman's wants a additional $400 to fix the AC! the first repair caused the second issue but casman will offer no refund or free repair to fix the AC. $300 for one month of AC use. Casman runs a SCAM beware.

This is the first time I have had any occasion to write a negative review. I'm not happy about it and I'd like to spare someone else the same headache. I took my 2006 Tundra in on a check engine light. Chose Casman's because of the Yelp reviews. I was charged a $140 diagnosis fee to be quoted a $589 repair needed to pass emissions testing. The mechanic was very hesitant to explain the diagnosis process and the purpose of the repair and even more hesitant to explain that the truck would run just fine - it simply wouldn't pass emissions. So I got a second opinion at Quality Auto

My family has taken our cars to Casman's for years. Chuck and his whole family are wonderfully helpful and treat my whole family like a part of their extended family.
Being a lady its not always easy to find a mechanic where you feel safe and respected but at Casman's I've never felt cheated or stupid. They are really willing to explain the problem and tell you the best way to fix it, they are also very good with pricing and are always honest with you.
While I now live in Austin, TX if it was possible for me to take my car to Casman's I still would. Chuck and crew are wonderful

I took my car into Casman's because my check engine light went off for some misfiring cylinders. Chuck, one of the mechanics, and took a look at my car, and recommended I check the battery first, then bring it in if that wasn't the problem. After cleaning the battery terminals, my problem was solved, thanks Chuck. With an immediate engine issue, I didnt have the advantage of mechanic recommendations, so I was happy with my experience at Casman's that I would easily take my car back there.
The only problem is they are not open on weekends.
