987 purchase advice needed

[JLL]

I'm strongly considering the purchase of a 2007 Boxter S (or 2008 if I end up ordering) and I have a few questions that I would appreciate help with.

1 - I would like to have an aftermarket nav system installed in the car after purchase. Does anyone have recommendations regarding what systems are a good fit for the Boxter? I've been considering the Eclipse and Alpine models.

2 - If I go with an aftermarket stereo, is it worth getting the Bose surround upgrade? I've heard that the Bose speaker systems can be a pain to fit to aftermarket stereos (that is the case with my 350z, at least).

3 - What is the typical lead-time on a Boxter order? I heard 4 months or so for a 2008 S from a local dealer, though that seems a little long.

4 - Does anyone have any comments regarding whether or not PASM is worth the money?

Thanks very much for any help! Having a nice forum like this to go to for advice is definitely a plus for the Boxter,
