Picked up my Sig 3.2 V6 today

[parttimer1]

Evening

Picked it up this morning and in love with it already. Its a 3.2 Elite with the slightly lowered suspension pack, drives stunning and as motorway miles home averaged nearly 35mpg which was impressive.

Anyways, some quick questions which my half-arsed searches didn't find quick answers to:

One of the back light lens has a small hole and crack - is it Signum only rear lights or can I put Vectra ones on? Thinking of smoked lens.....

LED dash kits - I'm far too far from the guy on here that has fitted for some members. I'm not bad at that kind of thing so is it a realistic DIY job considering I've never done anything with a Vaux dash?

Has 64k on the clock (genuine so far as checks prove), is it still 80k for the timing belt?

Nav CD is 2004, how much am I looking at for updating the firmware if needed and a later map CD?

Thanks in advance guys, did a lot of reading on here pre-purchase and seems to be my one stop shop for my Siggy needs.

*Edit.... oh and HID kit, how easy to fit?
