When our check engine light came on, revealing a leak in the evaporation system, Scata's did a thorough inspection of the car and found a number of issues with the brakes and recommended a transmission flush. I opted for the smoke test to find the leak and replacement of dry-rotted brake lines and they did not pressure me on the transmission flush and front brake job (brakes were relatively new but the car sits idle for most of the year). The work was done by the end of the day and they didn't charge anything beyond the smoke test fee to seal the leak.
