Did you sell the '16 ? I was fallowing your build. My Dealership has a Grabber Blue Mach 1 on the lot with Recaro's but an A10 . I'm thinking now is the best time for getting an Mach 1. I still think based on Motortrend test that DH HP will do faster lap times than Mach 1 HP stock mostly because it's stop faster and does 1/4 mile 0.6 sec faster than a Mach 1 HP. Also the new steering looks like a huge improvement compared to Mach 1 and S550's. But the price difference should be enough to make an Mach 1 faster and saving money in the process. So Mach 1 is a much better deal.I can't get into this "dark horse" stuff at all. To me that's just selling the sizzle. The extra weight over the S550 is a big negative, the existing car is already too heavy and the new one is heavier again. Made my decision to buy the Mach 1 easy. Plus big discount on outgoing model helped too!
Picked it up yesterday, what a difference from the '16. The built in rev matching works really well, I was very surprised by that, first time I've had that on a car. But I prefer to do it myself so it's turned off. I can vary the duration and intensity of the blip better than it can, it usually just gives it a big sharp handful of blip and that's not always what is needed.
