Used Cars for Costa Mesa Buyers

Costa Mesa, home to South Coast Plaza and the OC Fair & Event Center, borders Irvine to the west. The I-405 and SR-73 connect the two cities, so a test drive in Irvine is usually a quick trip.

Costa Mesa's sales tax rate is the same as Irvine's, and the DMV and smog rules are the same anywhere in Orange County.

Costa Mesa tax and registration basics

Costa Mesa's sales and use tax rate is 7.75% (CDTFA table effective October 1, 2026). It applies to the purchase price based on your registration address. On top of that you'll pay DMV registration and transfer fees, which vary by vehicle. Use the DMV fee calculator for an estimate, and see California registration fees explained for what each line item means.

Choosing a car for coastal Orange County

Being near the coast means milder temperatures than inland OC but more salt air and sun. A few things are worth thinking about:

• Convertibles make sense here. Plenty of Costa Mesa drivers enjoy a soft top. See best used convertibles for Southern California, including the 2018 Ford Mustang EcoBoost Premium Convertible we have listed.
• Sun protection still matters. Read protecting a car from the Southern California sun.
• Parking. Many Costa Mesa apartments have tight or assigned parking, so measure before you commit to a full-size SUV.

Paperwork

The seller provides a valid smog certificate, the signed title and a bill of sale. You report the transfer to the DMV within 10 days. Our title transfer step-by-step guide shows where everyone signs.
