Our story
Oceanside's Straight-Shooting Auto Shop
We started Filly Willy Auto Care to fix cars the way we'd want ours fixed: tell you what's actually wrong, skip the parts you don't need, and get you moving again fast.
When a driver's check engine light comes on before an 1,100 mile road trip, we get them in same day, run the diagnostics, and only replace what's failing. If a trim piece is loose while we're under the hood, we snap it back into place before handing the keys back.
Whether it's a dead battery on a road trip through town or a full tune-up, we treat every car like it has to get someone home tonight.
- No unnecessary parts or upsells
- Same-day diagnostics and repair
- Walk-ins from other shops welcome
- Located on S Tremont St in Oceanside
What customers say
“Filly willy is my go to everytime i need work done. They take care of business. Give them a try and you would feel the same.”
“Could not recommend this shop more. The owner got my car in quickly, found the problem, and replaced my spark plugs and coils in under an hour. 10/10!”
“I was told the truck needed all new O2 sensors. I dropped the truck off that morning and later heard from him that the truck was no longer giving any errors and he didn't want to replace parts that weren't needed. I appreciated the honesty and not charging me for services that weren't required. He was also nice enough to fix a piece of trim that was broken in the truck.”
