Seems like a good deal, but I'd say to anyone before getting tempted with the idea of one, give one a test drive. I did, expecting it to blow me away after all the reviews, but I didn't gel with it in the hour I managed to get a drive for. I think I missed the interaction of a manual too much. Maybe you need to have one for a while to appreciate it (Harry only seems to review cars he's been given for a few weeks). It's a shame real potential customers are lucky to get an unaccompanied drive, compared to journalists and "influencers" that seem to just be given the keys, but that's the same for all new cars.
I was looking at a daily driver, and for me it was just too impractical, but if it's a weekend toy then that's very different.
Also, it's double the price of a GR86, to me it's not twice the car. Finance deals though are very tempting, which I guess means they must be eager to move as many as they can.
