Hi New to this site & haven't built a model in 30 years but my son has found a huge interest. I recently acquired some 20-30 y/o nascar & open wheel race car models. All are new in box, some sealed. Is there a book published that will tell me the value of these cars or any I may buy/find in the future? are they worth more not built & new in box? I don't want to open & possibly ruin a good thing, I can go to Walmart & get us started. Thanks Jerry
