I have ran into this situation plenty of times where a shop or individual has been working on the car then asks for half payment before car is done, each time it didn't end well.
Currently my RX-7 is in for paint (been in for 6 weeks), I get a call today saying that they need half of the money because guys need to get paid. Car is more than half finished. I wasn't told about paying half of the monies before I left the car. They said, if i don't pay...car will be put back till end of September or after.
I just don't feel all so good about paying before job is done. Usually what happens is final price goes up after half payment, then you are in a situation you don't want to be. Price has already gone up good bit from what i was originally quoted, but i understand in business like paint nothing is solid until they start working.
It's a local, reputable paint shop. Some really good work has come out of there.
Thoughts?
