I trust Ray (the "R" in R & I, I think). This business is awesome. There's no B.S. and no upselling.. Just great mechanics and great service and prices that make you wonder if you're actually in Marin or not. Ray's crew showed me that my "Check Brake Lights" message kept coming on because the brake light had gotten too hot (a known issue with my car's make/model) and told me that they could jiggle the wires and get the brake lights to work (a temporary fix -- which they did for free with no diagnostic or look-at-it fee) or to fix it it would mean replacing a part. They told me how much and there was no pressure to have it fixed. Another one: my car flashed something like "Emergency Failure - Oil Pressure -- turn engine off". Baaaad. And it was Monday... on my way to work. So I pull in and Ray runs a quick diagnostic, changes the oil (my bad... overdue), and I was in and out in 20 minutes. Car all better. Gave me a discount even though I didn't have a coupon. Says "Your car is burning some oil. Come in every now and then and we'll check it and add if you need it." Really great place. The "waiting room" is smaller than a bathtub, so if you're going to "wait", walk over to Scotty's Market (free fresh-popped popcorn) or grab a couple burgers at Weezy's Grass Fed Shed. My car, my husband's truck, and my mother-in-law's car all go to R&I. I really trust R & I. Good people, good business.
