A brand new one will set you back $45K+ easy (depending on trim level) & as soon as it's driven off the forecourt, you've just lost cash (unless you can get a great deal).
You could go down this avenue.... Spend the cash, get if fixed, sell it (or trade it) & spend the cash on a newer 2nd hand one. VE's & VF's are rocking up on the 2nd hand scene so you might grab a good bargain.
Or,
Spend the cash, get if fixed & keep it if you like your SS. Invest your cash elsewhere.
Cars are like women, you need to spend money on them for the upkeep to keep them going (and happy). The happier the woman, the happier your life will be.
I bought a VY S Ute very cheap that had great mechanicals but the body was a bit rough due to years of use. I've sorted out the paint & bodywork and it looks fantastic. Was it worth the money in the end? Hell yes! After 2017 we wont see anymore Holdens locally manufactured & I wanted to own an icon.
Good luck with your decision.
