I've always received excellent treatment at this Precision Tune location. I've been going there for many, many years. John, the manager, has always been extremely helpful and polite.
The Master Mechanic Mike at the Champlin location was so helpful and went above and beyond. He took the time to show me some things on my vehicle where others may have taken shortcuts. He genuinely cares about people and makes sure things are done right. He did NOT try to sell me unnecessary services etc that my vehicle did not need.
