These guys have consistently been honest and reasonable. They do what's necessary - without "piling on". This has been a family business (they've got some great pictures on the wall) since the 20s or 30s. Location is not that great (28th and Nicollet), but they'll drop you off (usually in your car) downtown. Last time in, I had an usual problem with a Toyota: the transmission reverse light would go on when the brake was pressed. The Toyota dealer did not have any explanation. At Frenz, he remembered a small circuit board in the trunk that controls the lights. While an outrageously expensive part (from Toyota), it fixed the problems with a low labor cost.
