Mate, your car is hardly modified! Unless the car is HIGHLY modified ie: charger, loads of engine work, expensive rims and a costly leather re-trim (even this you wont make anything like what you may have spent on it - it may if your lucky make it slightly more sellable) you will loose money on it end of story. If your desperate to sell it mate, I would recommend spending some money on it cosmetically, it doesn't look the most tidy example and a good weekend polishing and cleaning will add value and make it more desirable. In that condition and that price, I would keep looking. Just some frien
