There’s a lot of good advice already, sorry to hear how you came to have the car.
On that note, and considering that you mention a young child, how much additional stress do you want/need. Is it upsetting for your wife to see the car every day?(rhetorical question).
Any decent independent body shop will be able to repair those bumpers, but there are plenty on eBay in better condition at much lower cost than new. Having said that, it’s probably cheaper for the body shop to repair those bumpers, than buy replacements to repaint. It’s amazing what they can do with plastic welding etc these days. Ideally, you’d want some ‘close to perfect’ in the same colour to swap over, to save repaint costs… which is easier said than done, and then you might have colour match issues.
The seats are repairable, it’s not that difficult to pick up a decent set of alloys/tires that don’t need refurbishing etc. etc. - But it’s all time and effort, and extra stress.
I have bought project cars before, as have many on here, but I’m not in a position to do so currently due to time and space. WBAC would be good to get a low valuation for probate purposes, but as for actually selling either get it repaired via an independent, or sell it it as it is via these classifieds, EBay Classified add with best offers or maybe FB market place.
It’s a tough one, but you could end up shelling out a load of money, facing lots of stress and then not making that much more after costs than if you try and find it a new home as it is.
