The Adam also seems intimidatingly small on the highway, despite the high population of B- and C-segment cars on European roadways, evidence a minicar is a minicar wherever you might drive.

So in short, if regular cross-country jaunts are in the books, there might be wiser choices than the Adam, but few better for the city and probably none more fashionable.

Our tester was outfitted in bright yellow paint with a contrasting white roof and white exterior mirror caps. White wheels and a smiling white bar cutting across the grille give it a cheerful demeanor. Black trim at the base of the greenhouse gives the Adam’s roof a floating appearance.

The chrome Adam script at the base of the C-pillar is a notable detail, and an Opel “lightning” badge at the rear of the car doubles as an innovative hatch release.

Inside, the Adam we tested carried over exterior accents with attractive white stitching in the door panels and matching inserts to the dash, shift knob and parking brake. The rearview mirror also featured the same white housing and black “paint splash” motif as the exterior mirrors. There’s a good bit of front-row roominess.

A “starry night” roof panel steals the show, though. It’s a feature normally reserved for cars more expensive than one priced at €11,500 ($15,955) and gives the Adam’s interior a unique flair.

Second-row seating is unsurprisingly tight, but rear seatbacks flip and fold in a 50/50 split to open up a fair amount of cargo space.

The Adam’s award-winning infotainment system, which in other trim levels includes items such as a 7-in. (18-cm) touchscreen with navigation and access to Internet radio, paired easily to an iPod for crisp, clear driving music.

So while not altogether perfect, the Adam scores highly on a number of fronts, leaving no reason to expect its shortcomings will not improve right alongside Opel’s fortunes.
