Byron's full-service shop on Placentia Ave. The estimate always shows its work, and the work you don't need gets talked out of, not sold.
Services
The estimate, itemized.
Full-service repair and maintenance. Every line gets explained before you approve it, and the lines you don't need get crossed off in red.
Engine diagnostics and check engine light
Proper diagnosis first, parts second. You hear what is wrong and why before anything is quoted.
Brake service
Pads, rotors, and full brake inspections with honest measurements, not scare tactics.
Oil changes and scheduled maintenance
Factory-schedule maintenance that keeps the car reliable and the warranty intact.
Electrical and battery
Batteries, starters, alternators, and the wiring gremlins that strand people at the worst times.
Steering and suspension
Shocks, struts, and steering work for a car that tracks straight and rides quiet.
Heating and air conditioning
AC that actually blows cold and heat for the two cold weeks a year.
Transmission service
Service and repair for automatic transmissions, quoted after diagnosis, never before.
