I go to Germany several times a year and travel by car. I have an Audi SQ7 that I use at my EU office. It's not the fastest thing but it's faster than most cars on the road and I rarely get an opportunity to go over 200kmh on the autobahn let alone 250kmh. The SQ7 tops out at 266kmh and it's very rare that I managed to go that fast for more than a minute or two.
I just don't see how, even in Germany, slow acceleration above 250kmh is relevant to the ownership experience for a car having a primary focus on track, not top speed. It's been pretty obvious that the aero is on this car is to aid downforce not high-speed acceleration, thus the likely trade-off.
Also, the potential for profit (likely to outpace the market) when the time comes to sell is very high so you could have held on to it so you've also foregone a pretty nice payday.
Gonna call it like I see it: Giving it back ain't adding up.
