It would be impossible to quote a figure on custom work such as this. Depending on your local shop prices and the quality of paintwork you could live with the price can vary by huge amounts. Best to visit some local shops instead of the internet to get some pricing ideas.
im pretty sure you cant lower that car if you do your steering and suspension will fail to operate your paint will very by shop blak is the hardest to paint and shop very extremely if i said 4999 that at some shops is a low number
the cheapest would be to look for forums that mod your vehicle they would know parts even cheaper drop kitts or a combo pf aftermarket drop kit parts to drop your car that low.. if you live in areas that are bumpy etc I suggest not too.. but its your car.. & for the paint you maybe looking at 500-3k depending on where who you get it done at..
Go to a couple auto body shops and ask for estimate(s) it doesn't cost and everyone has different price(s)...
I have a dark silver blue 2007 Saturn Ion. How much would it cost to have it lowered about 2 or 3 inches and painted black
