I would look for one or two of them on ebay that are being sold in auction form and add them to your watch list untill they end. it will give you a good ideal about how much it might be worth. Or you can watch a few that have been listed with the buy it now option and see if and how long it takes the seller to sell the. 3rd option would be find sombody that has the model kit price guide book.
yea I also didn't like only the top ten cars getting awards. I would rather pay a few extra bucks to enter in the show to get the 1st 2nd & 3rd awards back for each class next year. Wish they would have mentioned in the flyers or there facebook page that it was top 10 style show I wouldnt of even entered my car curb side can't really compete with other classes. Don't get me wrong I still had a good time and had fun seeing all the cars and would hate to lose the show its just going to be a really hard show to build for now and not sure if I can build a top 10 car in 1 years time and if I can it will only be 1 car entered for the show. My last best of show winning model took 3 years on and off to build. guess I better get to work
