Hello, looking for a shop to do a restoration on my 70 R/T.The shop I'm currently looking at. Are backed up for about 18 to 24 months. They want $2500 up front to put it in line. Is this normal? It's a non refundable down payment to make sure I take it in. I understand that the shop is just trying to make sure the work is there. But a lot of life can happen in 2 years. Health, accidents, ext. Just wondering if this is a normal deal with most shops
