Is It Better to Buy a Used or New Boxster?

Prices for a 2019 Porsche Boxster start at $59,000, which is less than the average price of a 2018 Boxster ($71,600). However, the 2019 price jumps considerably if you want a higher-performance model like the Boxster S ($71,400) or GTS ($82,800). There aren't any notable changes for the 2019 model year, so you may want to shop around and compare the prices of new and used models to find the best deal.

The Porsche Boxster was fully redesigned for the 2017 model year. For 2018, Porsche added a new GTS trim with 15 more horsepower than the Boxster S. However, if you’re interested in the standard Boxster or the Boxster S, you can buy a nearly identical 2017 model instead, which likely costs less. Boxsters from 2016 and before are noticeably different. Updates for 2017 include a different group of engines and trims, a retuned suspension, more responsive power steering, new interior and exterior styling, and a standard 7-inch touch screen.

Which Used Porsche Boxster Trim Is Right for Me?

The 2018 Porsche Boxster comes in three trims: base, S, and GTS. The main difference between the trims is the engine; the Boxster S features a larger turbocharged engine that puts out an additional 50 horsepower than the base model. The GTS is more performance-focused than the others, with a 365-horsepower engine. The Boxster S is the best choice for people who want a little more get-up-and-go compared to what the standard model offers.

When it was new, the Boxster offered plenty of features beyond what came standard. So you may find 2018 models equipped with dual-zone automatic climate control, 14- or 18-way power seats, heated seats, navigation, a Bose audio system, a Burmester audio system, and performance upgrades like ceramic brakes and a dual-clutch automatic transmission called PDK.

  • Porsche 718 Boxster: The base trim Boxster comes with a 300-horspower turbocharged four-cylinder engine, rear-wheel drive, and a manual transmission. Standard features include partial leather upholstery, a 7-inch touch screen infotainment system, Bluetooth, a six-speaker sound system, satellite radio, HD Radio, a rearview camera, front and rear parking sensors, automatic climate control, and a power-folding soft top.
  • Porsche 718 Boxster S: The Boxster S comes standard with a 350-horsepower turbo-four engine and most of the same features as the base Boxster.
  • Porsche 718 Boxster GTS: The Boxster GTS is a new trim for the 2018 model year, and it features a 365-horsepower turbo-four engine.

What Does Porsche's Certified Pre-Owned Warranty Cover?

Porsche offers a certified pre-owned program for vehicles 13 years old or less and with fewer than 124,000 miles. Eligibility is determined by the vehicle’s initial sale date. For its certified pre-owned vehicles, Porsche extends the original new-car warranty to six years or 100,000 miles. If the CPO vehicle is past its original new-car warranty term (four-years/50,000-miles), Porsche will cover the CPO vehicle for two years with unlimited mileage. Each CPO Porsche must pass a 111-point inspection. Additional benefits like towing and roadside assistance may be available, so read the Porsche warranty page carefully.

Porsche’s CPO program is below average for a luxury carmaker, according to our research. Audi, Mercedes-Benz, and Jaguar all have better programs.

2018 Porsche Boxster Versus the Competition

Which Is Better: 2018 Porsche Boxster or 2018 Porsche Cayman?

The 2018 Porsche Cayman is basically the coupe version of the Boxster (or if you prefer, the Boxster is the convertible version of the Cayman). These Porsches were developed together, and almost everything about them is identical. Both models have the same high-tech features, posh cabin, engine and transmission choices, and chassis. The Cayman is a little more rigid, but for the most part, the two cars handle and drive similarly. They even have the same predicted reliability rating.

Which Is Better: 2018 Porsche Boxster or 2018 Mercedes-Benz SLC?

The 2018 Mercedes-Benz SLC is a solid convertible, though it finishes behind the Boxster in our luxury sports car rankings. The SLC has a powerful engine lineup, a top-notch cabin, a long list of features, and more trunk space than the Boxster. The Boxster is far more agile, but the SLC holds its own and offers a great ride. In the end, the Boxster is the better sports car, but the SLC is an attractive value if you want a luxury convertible.

2018 Boxster Performance

How Does the 2018 Porsche Boxster Drive?

Every Boxster features a turbocharged four-cylinder engine. The base model’s engine has a little turbo lag, but it accelerates quickly and feels fast. Boxster S models have 50 extra horsepower and feel even more energetic, though they too have a slight turbo lag. Finally, there's the Boxster GTS. It has the same engine as the Boxster S, but it puts out an additional 15 horsepower. All engines come with a manual transmission, which is always nice in a sports car, and the available PDK seven-speed dual-clutch automatic is outstanding.

The only negative regarding the Boxster’s powertrains is the engine stop-start system. It’s designed to save fuel, but it can feel harsh when the engine turns on and off. Fortunately, you can disable it.

Spoiler alert: The Boxster is incredibly fun to drive. It delivers agile, buttoned-down handling that most cars – including other sports cars – simply cannot match. The sharp steering and sturdy brakes enhance driver confidence on winding roads. And despite having a sport-tuned suspension, the Boxster rides smoothly. A number of performance upgrades are available, including an adaptive suspension (PASM), speed-sensitive power steering, torque vectoring (PTV), and racing-inspired ceramic brakes.

  • Base engine: 300-horsepower turbocharged 2.0-liter four-cylinder (Boxster)
  • Available engines:
    • 350-horsepower turbocharged 2.5-liter four-cylinder (S)
    • 365-horsepower turbocharged 2.5-liter four-cylinder (GTS)
  • Drivetrain: rear-wheel drive
  • Transmission: standard six-speed manual; available seven-speed dual-clutch automatic (identified as the Porsche Doppelkupplung, or PDK)
Does the 2018 Porsche Boxster Get Good Gas Mileage?

The Boxster’s best fuel economy comes with the base engine. Compared to the rest of the luxury sports car class, this Porsche gets above-average ratings. The numbers listed below are with the manual transmission; with the available PDK, fuel economy jumps up by about 1 mpg.

  • Boxster: 21/28 mpg city/highway
  • Boxster S: 20/26 mpg
  • Boxster GTS: 19/25 mpg

2018 Boxster Interior

How Many People Does the 2018 Boxster Seat?

The 2018 Boxster seats two people. The cabin looks good and features plenty of premium materials, giving it the elegant feel you want from a luxury sports car.

This Porsche features a user-friendly interface, and the touch screen's crisp graphics make it easy to see and read. Apple CarPlay is available, and while many rivals have Android Auto, the Boxster does not. The convertible top can be raised and lowered efficiently while driving at lower speeds.

  • Standard infotainment features: a 7-inch touch screen, Bluetooth, a six-speaker sound system, satellite radio, and HD Radio

2018 Porsche Boxster Dimensions

Porsche Boxster Cargo Space

The Porsche Boxster is a midengine car, so it actually has two trunks. The rear trunk has 4.4 cubic feet of space, while the front trunk (or “frunk”) has 5.2 cubic feet. That’s a good amount of total space for a luxury sports car, but it's still not enough to carry any large items.

These cargo dimensions are for comparative purposes. There is no substitute for visually examining the storage area in any car you’re considering.
