Car Rental for 18-Year-Olds in San Diego
CMW Car Rentals welcomes drivers 18 and older — no under-25 surcharge, no age penalty, ever. Cash and debit accepted. Unlimited mileage.
No Under-25 Fee — Ever
Most national chains charge $25–$35/day extra if you're under 25. CMW charges a flat rate regardless of age.
Cash & Debit Welcome
CMW accepts cash, debit, and credit. A refundable deposit is required for cash/debit rentals.
Unlimited Mileage
No mileage caps on any rental — daily, weekly, or monthly.
Why 18-Year-Olds Choose CMW
National chains like Enterprise, Hertz, Budget, and Avis all require drivers to be 21+ or tack on a $25–$35/day surcharge for under-25. On a 7-day rental that's $175–$245 extra just because of your age.
CMW has been renting to San Diego drivers 18 and older for over 20 years with no age penalty whatsoever.
