40K sounds pretty reasonable for nicely done car (luck of the draw this one isn't reported as such).
but if you stand back from that big number and break it down they were very likely upside down on that car. when paint jobs are 20K there's not a lot of meat left on the bone to tackle the other aspects of the car.
think about this, if a shop put two guys on car for a full week that's 80hrs of labor at, let's be reasonable, 100/hr so you're looking at $8000
it adds up quick!
