Other than that I would not be selling it because of the eventual rarity of these cars with only a two year run of 89 and 90 and less than 3500 each year produced in only two colors red and black.
FWIW they made 3725 coupes in 1989, and 3750 coupes in 1990, along with 1000 Sedans in 1990, for a total production of 8,475. (not as rare as they are made out to be) Coupes were available in bright red or black, with tan or grey interior. (black being the rarer exterior color and grey being the rarer interior color, black/grey being extremely rare) Sedans were available in Dark Red or White with grey interior. (Dark Red being twice as rare as white) The only 3 "options" were CD player, sunroof, and leather. (FWIW the car for sale in this thread has ALL options)
If the crossover is OEM as stated, it does leak. While it may not be noticable YET, it is cracked and will get worse over time. It can be repaired fairly easily but will crack again. Not a big deal as I still run a stock crossover on both of mine and had a stock crossover on my Turbo 3.1 swapped Lumina when I had that, but you just need to be aware that it IS an issue. Last I knew an aftermarket replacement unit that isn't prone to cracking is around $350. New OEM are out of the question at around $1100.
Also make sure the brakes are in proper working order. The accumulators need to be replaced pretty often (they are ~$100 for an aftermarket one, OEM ones are closer to $200 IIRC, aftermarket ones work fine but are bigger and dont fit as well IIRC). If the anti-lock or brake light is on, it likely needs either an accumulator or a master cylinder. Also the powermaster III master cylinder is very prone to cracking, and to replace it last I knew a reman one was around $600 (might be more I haven't looked in a couple years).
Also, check that the radiator is in good shape with no signs of rotting or leaking at all. Since the turbo GP'* got a unique radiator, they are hard to find, and a new replacement from the dealer is somewhere around $800 IIRC. I had one of mine re-cored a few years ago and even that was something like $250.
And as with any 88-96 GP (or w-body for that matter) make sure the rear brakes are in proper working order. It is pretty common for the rear calipers to seize up, so make sure to double check them to make sure they are working. With the crosslace wheels this can be easy to overlook if you are not specifically looking for it.
I know there are some other common issues I'm not thinking of off the top of my head here. But anyways, as long as you check out the things I mentioned above and it all checks out good you should be alright. Make sure it shifts smoothly as well as transmissions START at around $1800 for them and go up from there. Also make sure it doesn't smoke at all on decel or at idle as that usually indicates the oil seals in the turbo going bad meaning the turbo needs rebuild.
