The only real difference is that the Classic has more standard options like reverse, electric start, and hand heaters. Both have the same liquid cooled 500cc engine. Only the Indy Trail has a fan cooled 500cc.

What fluids to add to a 1993 Polaris Indy 500 EFI Snowmobile

This sled was meant to run hard and fast you probably are fouling out your spark plugs.
You can use any oil as long as it's snowmobile oil, it dosent matter if it's arctic cat oil or Polaris oil, it's the SAME
Probably the Polaris Indy.

A good price for a Polaris Indy snowmobile is around 5000 dollars. This is because it is a very expensive and worthwhile snowmobile to have as it is very fast.
