Should You Buy the 2018 Porsche Boxster?

Buy this one with confidence on reliability, as long as you can live with higher running costs. It holds a good standing, sits above average among 2018 cars in its comparison group, and ranks as the best of the eight scored Boxster years. The 2019 also rates good, but it ranks lower.

Owners have filed no complaints for this year, so there are no common symptoms or mileage patterns to report. Federal recall records list two recalls, covering air bags, the gasoline fuel system, and structure. Those records are the main thing to check. Independent repair-cost data puts yearly repair spending for the Boxster at $952, against $801 for its class.

Run the VIN through the federal recall lookup and confirm that both recalls were completed. Ask the seller for paperwork showing the work. The 2019 has one recall on record, so it is a fair car to compare, though it ranks below this year.

Compared to the 2019 Porsche Boxster, which scored 6 points lower.
