Just keep the Fox and buy another car.....then another...then another....then you can swap out as you want. That's how I have 5 cars.....all mine! When people call me stupid then whine how they are bumming rides while their new car is in the shop...I just tell them, when my car has a dead battery or whatever, I go back into the house, grab the next set of keys and cruise.
honestly i got "out of the fox game" for a few years when id had enough of my gt. Was nice driving around in something that didnt creak, or smell, or rattle, or groan. But if its any consolation, i just bought one a couple weeks ago because i absolutely had to own one again...and then i bought another one. These cars are enough of a pain in the ass that youre either going to love them forever or theyll quickly fade and youll get tired of them. Looks like youve got enough time and effort in your car to know the difference at this point, so good luck with whatever you chose
