So, was this a dealer waiver/form or a corporate BRP form is what really matters.  warranty is owned by BRP that dealer facilitates…unless you got an extended warranty through 3rd party.   

I'd check with other dealers. That sounds shady to me given the fact that it's not always accessible. I also would have walked away before signing. 

The jd800 and the jdx600 had the tuned pipe i believe. Hard to find those tuned pipes now. The 00 series went till 75' with ccw engines, 76-79 had the Kioritz engines and the spitfire had the kohler free air. 80-84 were the kawi fireburst engines. I had a mint unrestored 80 sportfire and smashed up the fibreglass hood on first ride. 

and no pictures?!?!?

Yes, it was very good 95% of the areas I rode. Some ice chop as you turned the bend to Kempenfelt, the odd small bit along the western shore closer to Kempenfelt and the usual stacks of ice chunks along the shore along Willow beach, but closer to shore and not an issue when you stay out from shore. Hardly any frozen ruts, possibly none that I came across I think. Pools of slush was not too bad either.
