From the business
In the shop's own words: “Straight Talk, Solid Work”
Cornerstone Automotive is a family run shop in Oceanside, run by Nico and his dad. When something is wrong with your car, we tell you exactly what needs fixing and skip the pressure to add on extra work you don't need. If a part failed, we'll show it to you or walk you back to the shop floor so you can see the repair for yourself.
Most repairs are finished the same day, or by the next morning at the latest, and our prices come in well below what you'd pay at the dealership for the same work. When we replaced a customer's transmission with a rebuilt unit, we backed it with a warranty that carried them the rest of their time in California and all the way home across the country.
Customers keep coming back, some for four years and counting, because they know our team will tell them the truth about their vehicle every time.
- Family owned, two generations
- No unnecessary upsells
- Same-day repairs available
- Warrantied transmission rebuilds
