Used 2018 MINI Convertible

When Mini returned to the U.S. market more than 15 years ago, it single-handedly transformed our perception of subcompact cars, proving they could be aspirational fashion statements and not just penalty boxes. Now, the 2018 Mini Cooper is practically a car line unto itself, boasting multiple engine configurations, 2-door and 4-door body styles, and even a convertible. All the engines are turbocharged, and from the lowly base model all the way to the zippy John Cooper Works editions, they’re fun to drive. Sure, other subcompact cars out there like the Honda Fit, Kia Rio, Ford Fiesta and Chevrolet Sonic cost thousands less and are arguably more practical. But none of those cars offer the customization, premium appeal, driving delight and outright charm inherent in every Mini.

Even the base Mini Cooper Hardtop 2 Door with its turbocharged 3-cylinder engine is enjoyable to drive. Granted, by today’s standards 7.3 seconds to 60 mph isn’t exactly fast, but it’s quick enough, and the turbocharged 4-cylinders in the Cooper S or, even better, the John Cooper Works edition are even quicker, whether you choose the automatic or the short-throw 6-speed manual transmission. All Minis benefit from a suspension that’s set up for fun driving, with quick steering and a tossable chassis that makes carving back roads genuinely enjoyable. Of course, getting to those back roads means driving down the highway, and here the Mini falters a bit. That quick steering that’s so fun on a mountain road makes the Mini feel twitchy and nervous on the highway. The sporty suspension results in a rough ride. And there’s no avoiding the road noise at speed.

The 2018 Mini Cooper Hardtop and Convertible have just the right blend of modern technology and retro kitsch. The big center display has the 6.5-inch infotainment screen, and below it are toggles and switches that look retro, but control modern functions. The front seats are thankfully one area where Mini has left things modern, and these comfy chairs are complemented by clever packaging and even an available head-up display on the windshield. Hardtop 2 Door and Convertible models can seat two in the rear, while the 4 Door can seat three across, although the center position is a tight fit.

Mini says the Cooper’s stance looks like a bulldog, but in the low-and-squat way, not snorting and drooling. It’s also why the Cooper handles so well. The 2 Door and 4 Door Hardtops are conventional hatchbacks, while the Convertible’s meager cargo area is accessed with a tailgate that can be used for tailgating. An "easy-load" feature lifts the lower portion of the fabric roof to create a wider opening, although it’s hard to get it back in place, so maybe just pack light. The Hardtop 4 Door is about six inches longer than the 2 Door, at a tidy 157.4 inches.

SMILES PER GALLON
The 2018 Mini Cooper, like its predecessors, has a long tradition of doing more with less, and that includes fuel economy. All Mini models achieve fuel economy in the 30-mpg range, and the miserly 3-cylinder in the base 2018 Cooper Hardtop hits the 38-mpg mark.

3-IN-1 CONVERTIBLE ROOF
The Mini Convertible is actually three cars in one. With the top closed, it’s a coupe, and opened fully it’s a convertible. But in addition, there’s a half-open mode that offers a sweet and airy in-between that slides the front portion of the fabric back like a panoramic sunroof.

A rearview camera is standard this year on all Mini models. It adds to the turbocharged 3-cylinder engine, 6-way manually adjustable Leatherette seats, leather-wrapped steering wheel, 6.5-inch Visual Boost Screen audio and information system, and automatic climate control on hardtop models. Convertibles get a power top. Sportier Cooper S models get a more powerful 4-cylinder turbo engine, sporty seats, run-flat tires, LED fog lights, larger wheels and tires and bigger brakes, and add features like a hood scoop. The high-performance John Cooper Works editions get an even more powerful version of the 4-cylinder, even bigger brakes and a stiffer sport suspension.

Minis are almost endlessly customizable when it comes to interior and exterior aesthetics, and with Mini boasting more than 10 million different combinations, we’ll just let you play with the online configurator. Instead, note that you can also get a 6-speed automatic transmission for all models, in addition to a navigation system, head-up display that projects driving information onto the windshield, an excellent harman/kardon premium audio system, and adjustable shocks to cut down on some of the harsh ride. An Active Driving Assistant features adaptive cruise control, plus it can warn of an impending forward collision, and even apply the brakes.

With just a turbocharged 1.5-liter 3-cylinder engine under the hood, the base Mini Cooper still gets 134 horsepower, which isn’t bad at all. If you upgrade to the Cooper S you’ll get a 189-horsepower 2.0-liter turbocharged 4-cylinder, and that same engine in the John Cooper Works edition offered on the 2-door Hardtop and Convertible puts out 228 horsepower, making it the most powerful Mini you can get. Every engine routes power to the front wheels, either through a 6-speed manual or 6-speed automatic. While it’s true that Minis sip fuel, it’s a good thing, since all of them require premium-grade gas.
