Hardtop - to buy or not to buy?

[Onad]

"The main reason people buy hardtops is because of the rear defroster. "

1. For those of you who use your 97-02 Boxsters as daily drivers in winter regions: Is the fogging of the rear plastic window a serious problem in cold weather?

2. Are all Boxsters "pre-wired" for the hardtop? In other words, will a Boxster that orginally did not come with a hardtop have all the holes/hook-ups? I imagine the defroster has to be plugged in somewhere.

As background, I live in the NE and plan to purchase a Boxster in the fall (2000+) as a daily driver. I really appreciate everyone's comments. This forum has been invaluable to me as I research my future purchase.
