Harley makes a good bike and people mod those also. You own a 911, I don't think there are many other cars besides the mustang that have been modded, upgraded or changed in some way? P cars are being modded every day, and so are many other GREAT cars. Tuning and aftermarket mods is VERY LARGE in the US and in Europe. The tradition of Tuning cars has been around a long long time, remember HOT RODDING, well now its called tuning. The great thing about Hot rodding or tuning is that not everybody has to do it. If you don't want to change your car don't. Than't why.
