I may have an opportunity to become a partner in a 1999 M20S Eagle. On paper, low engine and TT and very well equipped. I currently fly a Grumman Tiger. I am looking for advice as to the difference in operating cost. Am familiar with the difference in fuel burn but would like to hear from long time owners of this model as to average annual cost, major problem areas etc. Tiger is not the fastest plane in the world but is a ton of fun to fly and very low maintenance cost so if anyone has time in both models and can give me a quick comparison that would be great as well. Thanks for your time.
