I took my car in to OSAC today. I drive a 2010 Mazda3. I haven't had any maintenance except regular oil changes done on it since I bought it in 2009. I thought it had brake problems, and possibly engine trouble. But OSAC said everything looked great and did not charge me for any more work except a 4 wheel alignment which I did know I needed I got treated like royalty. Jerry, the owner, drove me back to my house, and he picked me up when my car was ready I live in Glendale. Not only did they not add expensive repairs, but they washed my car insideout, and vacuumed the interior it really needed it too! Didn't charge me a dime for this. I will definitely be taking my car back here on a regular basis.
