Why are Maaco paint jobs so cheap?

Having worked at a Maaco for 7 years while going to college ,I can say that if you expect a paint job to last 10 years while spending $250, you’re crazy. However, if you do like the OP did and do all the prep work yourself, sanding all of the cracks and crevices, you’ll get a decent job for the price.
