Does anyone know why some models (mine for example) have the radio antena on the rear panel and some don't?
What do you mean by rear panel?I assume you are talking about the cupes and spyders. The early 2002 models of the coupe for sure, and maybe also the spyders, had the radio antennas on the rear fender. Late in the model year, they went to the antenna in the glass and it's been there ever since. Hope this helps.
