Until recently, it WAS an early NSX, but they went $$$$$$ a few years ago.
Now, it's my daily, a 2016 Cayman S, but only if I had to make my daily driver my track car, too.
If I could only keep one of my track cars, it would be E-Street 2003 Miata LS. I'd take it over the Panoz GTS-WC with the LSx and Jerico, the '98 Monte Carlo Jimmy Spencer Busch car with the Joe Gibbs engine, the C2 Vette vintage racer that won podium spots at Monterey, the track-prepped 944 with the 968 3.0l swap, the Spec E36, the Spitfire with the 13B swap and 510 IRS, the Merlyn Mk11A and the '22 C8 Z51.
That said, I was ready to chop it up to make an Exocet, so can I really be trusted? hahahaha
