Paint Quote - What is Reasonable?

[tutone]

I am sorry. 20K or 15K sounds completely out of line.
I went to trade school/body shop in the late 70s and early 80s. I opened my shop and painted a guy's Matador red 57 Bel Air in single stage enamel for $1500 bucks. Allowing for infation in today's money, that is $5300 or so.
Ok apples to apples, 1980 a 72 Super could be bought for 3500 in relatively good shape, I know, I bought one. Now by all the same inflation calculation, that would be around 13 K.
But.... The difference is. They don't make 72 Supers any more, so supply and demand takes over.
That being said, they stay up nights making auto paint and as long as people buy it at their inflated price, they will keep selling it.
I will attach a picture of a locally painted 57 from 2013. The body work and all was included. This was a 90% straight car and the total price was 4500 bucks.
I would get references and shop around and look at some people's work.
