Fold it up and tuck it in there. Or hide it somewhere lol
This makes me nervous because I'm in the process of buying a used '19 Autobahn from Carmax. I'm crossing my fingers that it hasn't been modded. Only 10k miles but who knows.
Order an OBD11, it'll tell you how many times it's been flashed.
Then match that to the number of flashes the dealer has on record. If an early 19, it'll have had 2 patches flashed.
Do this before your return period with carmax.
