Mach Z 780

I have an opportunity to trade my 95 XCR 440 for a 94 Mach Z 780 with 4800 miles, a 136x1.5 track, and m10 suspension. The only thing is it has some rips along the seams of the seat. I don't know a whole lot about Ski Doos as I am more of a Polaris guy. What are the pros and cons of this sled? Are they somewhat reliable? What should I be looking out for if I do the trade? Any opinions, info, or specs on this sled would be appreciated. Thanks
