Stop flexing how the UK gets the better Hyundai product offering.
First you get the i20N, I30N and the i30N fastback. You get more color options for all your N models.
As for the Kona you get forged wheels. You get front vented seats, rear heated seats, heads up display, deep snow, sand and mud modes, moon roof, heated steering wheel, I believe passenger power seats, ugh...not fair. LOL
I wish I lived in the UK just because you got more options. As for cost, what does a Kona N performance cost your way? Here I got my Kona N (because we only get one option which is the color) for $33.5K prior to trade-in or down payment.
As for winter, I need winter tires. We can get anywhere from 1" up to 36+" from a single snow storm. If I need to drive in that weather I rather play it safe than sorry. Though normally I use my Saab 9-3 Aero for the winter months as it tends to plow better than the plows do on my road. LOL.
