Totally agree. For the S-197 chassis, I prefer these to the Shelbys anytime.
Full story for another day but in 2011, when these came out, I was waiting for a small claims judgement against my insurance company. I bought my 2006 in spring of 2011 prior to knowing what the decision of the court would be. The decision only came in winter of 2012. I won.
At the time, I wished I had held off on getting the 2006 because I would have used the settlement to get into one of these. By then, even better, because the 2013's were out. I had already done too much to the 2006 to sell and start over. Oh well, I take comfort that my 2006 is now a pretty good match to one of these.
