Hi PD,
I am on the right side of 60 (ie 63) and I would endorse Yenn's comments.
I have had a Savvanah for the past 3 years, and have done around 220 hours in it so far. It has the long range tanks, holding 140 litres, which gives me at least 7 hours endurance plus 45 minutes reserve.
I would thoroughly recommend it if you like low and slow (I flight plan 90kts TAS), plus the ability to land and take off from shortish grass strips.
HTH,
Neil
