Is it possible to install cupholders on a 99 Boxster?

If I remember correctly, they can be retrofitted, but it requires a few parts. From the complaints I've seen regarding them, I'm not sure you'd want to do so. FWIW, I reasearched cupholders left & right and finally bought the dual cupholder tray that fits in the center console. Later I bought a Bird armrest. Sam Bird (BIRD Armrest Cupholder Home Page) still has a fe left and I suggest you call him about them. FWIW, Somewtimes I stil use the dual cupholder as it provides a place for my wife to put her drink when we travel. The two best benefits are the armrest and permant hinge (metal) that will not break or need repalcement.

I also use the duel cup holder tray from autozone, works well and is inexpensive. The only downside is that it does take up some passenger space.
