Buying a car in San Marcos

A few local things worth knowing before you go look at a car.

Get it inspected

A pre-purchase inspection at a shop you choose costs far less than one surprise repair. Ask for service records too.

Check the VIN

Run the VIN through a history report and the free NHTSA recall lookup before you go see the car.

Paperwork

Make sure the name on the title matches the seller's ID, and ask for a bill of sale. Check your state's DMV for what else you need.
