That Drivers side rear door has definately been sprayed as the main bottom part has been repaired and sprayed and then blended up wards so that all rubber seals etc dont have to be removed.
i was taught this trick by my paintshop tutor and have to admit when done properly it can not be seen unless on a difficult coulur like silver which has had too much black added to the mix
take some pictures at night with a heavy flash and that will prove it some times
overall though not a bad car although for the money i think i would of had a vectra sri 150
