I recently purchased a '01 Boxster S with the DSP radio option. With this option, the standard dash mounted cup holders are not installed due to lack of room. What is available for add-on cup holders?
I too just picked up a "01" and spent more time than I care to admit looking for and at the cupholder options available.
My conclusion that was echoed by many on this and other sites was the "Ultimate Cupholder" was the way to go. The clip on, hang off styles are not bad but are realistcally an accident waiting to happen. The ones that go in the arm rest storage are very cumbersome to get at and can cost a bunch.
The ultimate holder while resting on the passenger side of the shift console are actually a much easier reach that I thought . It has exceeded my expectations!
