When I was a kid the dragsters and funny cars were what got me into modeling. Sad they don't make em much any more. This might help a little. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXDYXX&P=W
Flea market finds $20. I owned a F150 JUST like the model so that was nice to find. I have never come across a Porsche model like that I think it might be worth a little something. If anyone knows let me know THANKS!
