'02-'03 Polaris 700. How are they?

[Grit dog]

Hey, new here, l'm looking at a couple Polaris 700's, 02 and 03. I've had Pol sleds and know a few guys with 500 Polaris quads that have a ton of miles on them. What's the consensus on the older 700's?
Good motor, they were new in 02?
How does the carb do changing altitude?
Anything else to know about these in particuler?

Thanks
