I test drove a new 2019 Signature today - have to say, it didn't knock my socks off like I thought it would. Yes, the car had plenty of power and definitely more spirited than my 2016 GT, but the total driving experience wasn't enough to make me want to trade up for the 2019. The leather seats were more comfortable, and the ventilated seats were the bomb! I read somewhere that the 2019 was about 1/2 inch lower than the previous gen, but I felt like I was sitting up higher (seat was in lowest position). It definitely had all the bells and whistles, but I think I'll keep my 2016 GT for now. PS - this car was just off the truck, so new that nothing had been programmed, and the covers were still on the wheels, plastic wrap on car, lol
