Hopefully constructive thoughts - I think it's sort of between 2 stools in having some visual hot rod elements like 7" rears and trim deletes but does not have the hot rod heart - and lacks other hot rod visuals such as sport seats. The heart is what that 'Sport Purpose' is all about. I think that narrows the likely market for the car immediately. The colour is a bit love it or hate it but what 70's colours aren't?

At the end of the day, you have a very nice car displayed for sale for a bit over a week on a very narrow appeal forum - it's not like selling a Honda or Toyota. These things take time unless the car is so definitively special that it can't be resisted.

Good luck with a sale as it does look like a nice car.

Cheers,
Mark
