Let's be honest here. Not all the people that want to make changes to their cars want to do so for aesthetic purposes. Also, most of those who enhanced their road vehicles early on did so to escape Revenuers. It's been a long time since Prohibition. Even so, the Model T was around 30 years old by the time that hot-rodders began modding them for barely legal high performance street use. I don't care how capable the guys at Lingenfelter, Callaway, and Saleen think they are... I'd prefer they allow the Model S to have been around a similar amount of time before they begin to 'bless' them with 'improvements'. If Panasonic hasn't come up with a replacement/alternative entertainment system for the Model S in all this time, I certainly don't want to see one from Alpine, Clarion, Denon, Kenwood, or Blaupunkt either. Concentrate on this part: We have not tested, nor do we endorse, such changes or products. ... Such unauthorized modifications could reduce the safety of our vehicles and any injuries resulting from such modifications could result in adverse publicity which would negatively affect our brand and harm our business, prospects, financial condition and operating results.
