That being said I'm sure even a 2018 or 2019 would be a blast to drive but I'm wondering if you just put a tune on a 2018 what kind of power levels do you get to? I'm guessing a tune 2018 would be as fast or potentially faster than a stock 2020/2021??
Aside from the difference in horsepower and some of the cosmetic changes like the upgraded Dash and headlights are there any substantial mechanical differences?
I thought I read that it wasn't just a change in turbos but that the actual engine is a different power plant in the newer car and I'm wondering if there was anything wrong with the motors in the 2018 2019's that could be something I should be concerned about if I bought certified preowned and plan to keep the car for five or six years??
