Well. the thing you guys dont realize, is unmolested cars are going to be the future, my original thought 20 years ago was a ss rear a 425 hp warranty jegs motor etc. etc. all these cars were done like that cause thats how we did em back in the day. Try and find an original car anymore.
Sounds like your looking for some big bucks and if you would post your expectations you will get rid of a lot of members like me. It's not an SS, you sound like you want to sell it as is, not running -driving. The last car I bought was a Monte barn find stored for 21 years. You don't really want to know what I bought it for but had to put a lot of money in it, brake system, fuel system, headliner, tires and the list goes on. Long story short is it wasn't an easy sell and only got $3000.00 for it, drive it anywhere. I've also had a 21,000 mi Regal, 52,000 mi GP LJ, the most I got was $3,600.00. I'm going to suggest you get it running driving if you want to get any kind of good money. One good thing is it does have a V-8. Since it was your Grandmothers you just might want to keep it. What ever you do - good luck.
