I have been doing business with Sparks for over 20 years. Why? Because I trust them. When I take my car in for oil changes, they don't push for "other services" (change filters, etc.) unless they really do need to be done. I can think of a couple times over the years where I took my car in, convinced something major was wrong - perfect opportunity for them to take advantage for a huge bill - and they said it was only a minor, inexpensive problem. And finally, their prices are fair. What more could you ask for from a mechanic?
