Not knowing anything about this specific car, on the surface of the ad it looks appealing. Only mods are suspension and wheels. Looks immaculate - low miles. Look at the garage, house, and the other vehicle - I think stuff like that tends to suggest how the owner maintains his cars. Would get a PPI for sure, and then let the negotiations begin. Assuming all is in order, think that the 30k price is in the right range. Good luck, and keep us posted.
