$1500 to $15000 depending on the current condition of your car and the quality of work your after.
If you car is in perfect condition with no dings or dents to remove and the paint is just faded, approximately $8000 for a factory type paint job. If the paint on your car is peeling or flaking off, it could be very costly to remove the existing paint. Painting over bad paint is pointless.
Cheaper paint work usually doesn't look good for very long because the surface is not prepped prior to painting and any small nicks or dings may result in the paint peeling. Cheap paint jobs usually does not include the removal of unpainted parts leaving behind unsightly overspray on chrome and rubber parts, eventually peeling from where the tape is peeled away. Cheap paint work can't be undone very cheaply, so think about it before you decide to do it.
