I have owned my Volkswagen Beetle since 2006. It had been in a private collection since new when purchased from Beetles UK in 1998, clocking up only 2,500 miles. It had only been dry driven, never in the rain.
Since I puchasd the bug, I have replaced all the chrome with good quality german products, fitted front fog lights and four stud four spoke BRM alloys. I have recently fitted CSP LED Rear Lights. One item I advise you to do to your beetle is waxoyle or black jack the inside/underside of the body and chassis, this will reduce the risk of rotting in key areas, and save you money in the long term.
Remember, any modifications you make to your Beetle should be passed onto your Insurance company so that you are covered in all eventuallities.
