The future

In 20-30 years I absolutely believe you will be seeing hellcats and demons doing for stupid numbers on whatever auction is around. Gasoline will still be around but we may have more electric cars.
Maybe. One never knows what the market will be like and what cars will be pulling big money. Lot of people tried this with cars from 25 years ago and it's not working. Super clean and low mileage cars from that time can't even sell for the original sticker price. As stated before the hobby is always changing and I don't see this trend lasting. Just look at cars shows. In the early 90s they were huge now the numbers aren't what they were. Yes still pulling in people but no where near 20 years ago.
