andy told me tires are only supposed to go one direction
Alaric S.

trying out a new repair spot! got a referral from my friend to give andy a try at walnut creek smog! i really appreciate the keen eye of noticing something so little and also giving me recs on how to go about our 200,000+ mile vehicle i didnt mind crossing the bridge and paying a little extra to pay andy a visit! for what he charges, the service requested and quality, car repair is definitely re-assuring! well done and thanks again!

See all
