I had a check engine light that kept coming on, and no other mechanic could diagnose it other that the one's at Ratzlaffs. I took my car in, they were extremely friendly and the guy I talked to knew his stuff. He was the one in the office and he seemed like he has been around cars his entire life. One of those types that cars just come easy to. Or at least thats my opinion of him. Same with the mechanics. These were no $10 an hour Jiffy Lube techs out of junior college. These guys were obviously experience pros. Anyway, they found the problem right away, and fixed it, and I have not had the problem since! I give them 5 stars for their niceness and know-how.
