This is just the practical side of me talking but if your salary was cut 20-30% why do you want to continue to pay more and more taxes by continuing to swap cars? Or even modify the car at all? GR Corolla, on a whole, (as much of this market) is incredibly expensive if all you need is transportation. Unless the other car order you have is something in the 20-30k range and even then I'm kind of curious what the strategy is here. Coming off a 650hp supercharged V8 to 300hp 1.6L is always going to be a disappointment. Haven't really seen a description of why the car isn't checking the right boxes for you so can't really say if the car even has the remote possibility of fulfilling what you're looking for.
In any case with a number of dealers coming down to $5k or lower markups today you're going to be hard pressed, imo, for your car to maintain its value because it doesn't have the LSD performance pack. The main consumer of that specific spec is the people who barely have enough money for the base car or people who want to modify it like crazy and put nicer LSD's in and not have the weight of the heating elements or tech package as they're tossing all the factory stuff into a bin gutting the car. Both of which are looking to buy the cheapest car they can find unfortunately.
