And it's only March.
Money really does buy happiness if you equate happiness with going around a track really, really fast in an ultra-high-tech supercar. And that's one of this year's biggest automotive trends so far: the track day (sometimes but not always street legal) supercar. Quite a few of them have debuted this year and there's clearly a growing segment here. We're not at all complaining; just look at what's new (and we're probably forgetting a few):
Porsche 911 GT3 RS, Porsche Cayman GT4, McLaren P1 GTR, McLaren 675LT, Koenigsegg Agera RS, Aston Martin Vantage GT3, Aston Martin Vulcan, Lamborghini Aventador SV (to an extent), and the Scuderia Cameron Glickenhaus SCG 003. Those are all just from Geneva, and we can't wait to see what the new Ford GT is capable of. So now we turn it over to you: what's your favorite track day supercar of 2015?
