Your service -- professional, mechanical and personal, has been and still is far and above the norm. I further appreciate the candid responses in: "I don’t know but I’ll find out." Too bad our politicians aren’t as forthcoming.

Sedona Car Repair Staff at RPM

We celebrate Redrock Precision Motors 12-year Anniversary in Sedona in August, 2018. Some things are just meant to be!

This is "Mayu" who belongs to Brandon Scheinuck. Mayu will be 12 years old on Valentine's Day 2019 and is a Border Collie Mix. She often went to work with Brandon, meeting and greeting automotive repair customers. Mayu is very talented and has quite the bag of tricks. Mayu came to Brandon as a pet sitting job that turned into a wonderful lifetime commitment. Karl is in the picture, not Brandon. Mayu is our grand-dog!

Mike, from the San Fransisco Bay Area, has been a car enthusiast his whole life. In 1983, he graduated from Monta Vista High School and the day after enlisted in the US Army Rangers. After training was over he was sent to Ft. Campbell KY and was assigned to the 160th Night Stalkers Special Forces unit. During his time there, Mike started working on cars and building engines for others while still in the Army. He was using the local machine shop "Lone Star Racing" to do all his machine work. When Mike's 6-year enlistment was up, Lone Star Racing hired him on as an OJT employee. He worked there building motors and cylinder heads for high-end NASCAR and drag racers like Bill Elliot, Ricky Rudd and John Force. After 7 years, Mike returned to California and was hired at Ellsworth Machine Shop in Mountain View CA where he worked and managed the shop for 24 years. The cost of living got so high there...$3,800 rent...Mike had to make a move. So, Mike and his boxer dog Larry found their new home in Sedona. They have been here for 4 years now and love it!

Come visit us at Redrock Precision Motors and meet Larry the Boxer...
