Sometimes it can be helpful to read a post carefully before replying.... OP, since you are looking at an early 2000s Beetle obviously warranty is not a concern on a 12 year old car. I would suggest finding a manual for the particular car since VOA has not always prohibited 4 down towing. When I had a 2012 Jetta there were no towing restrictions listed for the manual transmission and it specifically mentioned using a tow bar. My 2014 Passat manual specifically prohibits four down towing for either manual or automatic models. I have seen new Beetles being towed 4 down for many years. Like any towing setup, a quality baseplate that is properly installed is key.
