@clerks What's your suspension setup? Since you're in need of an alignment anyways, and selling the car within a year, and price+labor sensitive, how about going back to stock height now?
If you're on coilovers you could raise them up to stock-like height while still enjoying the handling and/or ride benefits, and then swap back to stock later. Since you're seeking an alignment now anyways, it seems like a good time to adjust coilover height.
If you're on lowering springs, and you're trying to minimize money spent on your Model 3 at this point since you plan to sell it, I really suggest swapping back to stock springs now instead of investing in camber arms and another lowered-height alignment. (Yes you should get decent money back selling used camber arms, but unless you manage to score a used set quickly, you're still going to lose $$$ by buying new and selling used.)
