Not too bad. Well, ok, with 64bhp, it isn't exactly sprightly, but happy enough on the motorway, as long as you don't want to go above 90mph. Ever. Oh, and overtaking is something of a spectator sport.
Going above about 4krpm doesn't make you go any faster, and it sounds pretty rough up to that point, so frankly you'd be a lot better off with a diesel. 'HTP' apparently stands for 'High Torque Power', which is presumably some sort of hilarious german-engineer joke.
It rolls a good bit, but grips as much as could be expected from 145 section tyres. Naturally understeers, obviously, but you can actually adjust the attitude of the thing as it squeals merrily through corners, which I wasn't really expecting.
Despite my best efforts, it hasn't died in the day since we got it. I have until noon tomorrow to complete that mission.
