[UK] Keep, sell or scrap? Black 206 GTi 180. 2004. 90k miles.

I've had my car for about 15 years. I loved it to bits and drove it everywhere upto about 90k miles. Then we started working from home and moved into a house with two parking spaces in front of each other, and my wife's new car always sits at the front. So my car's trapped in the back space, never gets used, is now SORNed, and just sits there deteriorating for almost 2 years.

Last time I looked inside the steering wheel and seatbelts started going moldy. The two front tyres are pancakes.

I feel like I should do right by it and restore it, get it valeted, and get it back to good condition (it used to be a beautiful car!)

But I can't afford it, (it'll be ~£700 to get everything back looking good) and I doubt it would be valued by anyone these days anyway as it's a thirsty N/A and does 25mpg, whilst not being any quicker than a standard newer car. So feel like maybe I should scrap it.

I'm frankly embarrassed how long it's sat there unused, my neighbors must hate it. But I can't afford to fix it yet, and don't even know if it would be worth the cost of doing so.
