2018 Porsche 718 Boxster
KBB.com Review
Kbb.com Expert Rating
Don’t be seduced by the larger engines and higher horsepower offered in some of the new Boxster’s rivals. The Porsche is a serious performance machine. Even the base model will accelerate to 60 mph in less than 5.0 seconds, and its athleticism is unmatched in the class. The Boxster is also polished and sophisticated, with a smooth ride, refined controls and a comfortable interior.
If the questionable security of a fabric roof isn’t for you, the BMW Z4 and Mercedes SLC have folding retractable hardtops, which offer superior protection from bad guys as well as weather. If all-wheel drive is on your wish list, check out the Audi TT, which is more than $10,000 less than the Porsche.
