Bought my 2010 a year ago, fully stock with 109k miles with the full intention of taking it to the track. 5 track days later, no regrets. I'm still a noob, but have learned a lot in my short time driving HPDE. Also, I have forced myself to do a lot of my own work, so the experience gained there is invaluable! I've spent way more than necessary on the car, but such is life
I've tempted selling it and moving to something like a full-blown track build(to save a few bucks), but I think at the end of the day, building something from the ground up is much more satisfying. Even if it does cost more.
