Visiting from LA for the weekend, car broke down unexpectedly in San Marcos, on a Saturday at 3 PM! Ralph, and Al were super helpful and accommodating. Very nice and genuine. Stayed past their closing time trying to help with the issue and even gave us a ride back to our Airbnb. Great business. Thanks Ralph!
