It will easily take $10k in parts and $5k in labor to make this even close to some of the $15-17k examples out there. Also note the jacked up dash, light switch, carbon, seats...it would be highly prohibitive time and cost wise to revive this. If you could get it for $7-8k and were happy doing lots of learned restorative labor then maybe...if you're retired or have lots of time. The fact you can get a great and very clean example for $20k shows this isn't worth much at all, too much damage done.
