I agree with Martin........I think 60K is just fine (even considering that it's yellow

).
You're competing against a lot of junk out there and shoppers are exposed to this junk (and resulting disappointment after disappointment) on a daily basis.
This is why good, clean, well cared for planes are selling so fast and this applies to all GA planes not just our 150/152's.
On a side note, I hope you share your CubCrafters with us. That plane looks intriguing and desirable.
Best of luck with your sale, Ron.
