I'd want to see examples of cars they've done for that price, found 2 private ex-shop workers who hire booths in QLD now who can do cars for around that mark for basic paint on a car that is in excellent condition with no damage to start with

but realistically broken down I have got the following done in the past:
$400 front bar, rear lip (also installed) and lip repainted
$80 for mirrors
$300 for a bonnet

as at the end of the day paint isn't cheap & plastic primer isn't cheap (for repainting that black crap looking plastic on door trims/licence plate surrounds)

painting is worth the extra money being spent on focusing on the fine details, it's an art form and costs accordingly on a car by car basis

soo many variables to look at does your car have:
rust that needs to be repaired
dents that have to be smoothed out
anything like this will see that price rise to a more realistic figure
