Why do you guys care if the prices go up because these knuckled headed TV shows like to do Broncos. For one it drives the value of a finished Bronco way up because everybody wants one. Also believe it are not there are very few and its getting to be fewer people that can actually do this stuff for themselves anymore. That means that these people buy from vendors which means that there is always a supply of parts. Anyone who built old cars back 30 years ago knows what I am talking about. Hours and hours of walking swap meets looking for parts that weren't available. Just have a wreck in a 32 Studebaker and see how long it takes to find fenders. But the net result of all this is that your parts and vehicle in your possession have gone up in value and there are always half finished projects that were over the head of the owner and paying someone to do it costs them even more. I bought mine for $1000 from one of those guys 8 years ago and sold parts on ebay he had bought and I didn't want for over $1500 by the time I sold it all. That stuff still happens but you might have to pay $5-$8K for the unfinished pile of name brand parts that if you bought them individually would have set you back $10-$15 K.
Personally I watch Fast and Loud for entertainment only I would never buy one of there vehicles. But I do not mind when the value of my bronco continues to rise and keep pace with the cost of a new vehicle.
After building cheap pieces of crap for years and havening trouble finding body parts after a wreck or odd ball chassis or engine pieces I decided I would never build anything again that wasn't popular. Broncos, Mustangs, 55-57 Chevys, A models etc. Every little part and piece is available for these popular vehicles and that's a good thing if you like them. it wouldnt be that way if they weren't popular and I really don't want to go back to spending my weekends walking swap meets or all my time search craigslist and ebay looking for a used POS that I will still pay an arm and a leg for because there is no other option.
