What should I be asking for my car? Part out, or whole?

As title says I'm just curious what you'd ask for it if you were me. Or if you'd part it out or sell as whole. Car runs but not right and I'm tired of fighting it cant find a decent tuner / mechanic who'll work on it, nothing feels wrong with it beyond all the codes it throws; Maybe un STS it? I don't know.

Major change from what it was is just rebuilt motor, throw out bearing, rest came with the car basically. Tons of pics if interested I bought it beat to death, when it had popped at an event. Been slowly restoring it for way too long, wanted a once in a lifetime super car (for me kids, wife mortgage, California, only worker in family this was my best shot, sold all other toys and haven't bought one since) I get it all back together and it just fights me.

2003 Z06, 100k miles Blk/Blk, 6spd I'm 3rd owner, 2nd owner was my half brother, very clean mechanically, the paint and body are below average imho. It has baseball sized paint blister on rear cover, both front fenders are damaged down low, couple big rub damages on bottom of car. It sits on stock rims which are a little beat up curb rash and such, dead rear tires, fronts not far behind 20%;
Interior is avg seats are split at a seam dash is ok, but plastic is ratty, not cracked anywhere obvious yet but brittle. Door cards are good; Hud works well, ac has a scratch, radio has done the ol' unpaint on some buttons.
AC is not working needs vacuum and charge.

I went through the entire car mechanically, it is super clean mechanically but the computers on this car are sucking and tuning has been difficult. It does run and drive just not what I would have expected, it was faster on stock motor with 6psi and cracked ring lands. STS wants 1000.00 to send me the original tune tho I still have the predator it lost tune car had.

That I think does it...
It is a California Car, it has EO# from STS, it pulls strong but is computer issuing me to death. I bought it with almost all of the mods on it and blown ring lands inow on a forged motor. I'm very confused this is my 7th lsx built car and the worst one ever by far. So disappointed and 4 years into a 3 month project. :( Sometimes it's best to let things go. What would you do, sell it? Part it out? Keep fighting? Dunno anymore.

If you have the space, time and ability to tear this car apart you will make more money but it will take time and money to sell all those parts. If it is that ratty I would ask 10k obo and field offers.

I know where you're coming from....sometimes you just have to know when enough is enough. I think though that you just need to find the right person to look at the car. Someone that has experience on the electrical side. Too many times you have great wrench turners but they might not be that strong when it comes to diagnosing electrical. As far as what you should do....that's tricky. I personally would start tackling each issue one at a time and not focus on the big picture just yet. You have codes so you're being pointed. It's a matter now of just tracing them down 1 at a time. I do understand though that at some point you have to just throw your hands up and write it off as a learning experience. Other than a psychological drain is it hurting anything by being torn apart? Financially or space wise? If not I would definitely start tackling it but if it's more than just a pain in the ass I would start shopping it around.

Thanks for replies first it's tough to part out sentimentally else I have no rush been sitting on another ls1 for years. Too me 10k seems low it does drive fair, it just feels slow to me and idle hunts which sound lopey. Cars other Ac needs a charge, and two rear tires with an alignment. Rest is all in the oddball tune and electric (sts for me has been hard to tune) interior has avg damage for 100000 mile car. Paint can be fixed up doesn't need a full respray or nothing. Sitting on a glovebox for 10 years meh, I'm in no rush for money but not my style. Just sometimes cars are anti owner/mechanic/project. I'm a solid wrench and above average electrical(so I thought anyway as I'm the one in my car friends group who gets it at all including efi); tired of this one and it's nonsense. Really want to known what grounds go where on the sp201 splitter behind batt box. Other codes seem nonsensical, or obvious. That's all in another post, got 1 sell it, 1/2 eye on prize 1/2 on part it out. ;)
