THIS SITE MAY NOT BE SET UP TO SELL YOUR PURPLE 1951 BEETLE, SORRY !
I believe that the age of that car is going to be too old for this site. I have not seen any classics for sale on here. I would try other selling avenues if I were you.
Yeah, try putting it on some of the classic car forums in the classified section. A custom job may not appeal to hardcore VW owners but you might generate some interest. Of course there is your local Craigslist.
