I've given up renting "Steam driven" aeroplanes in England and even America.......Especially when you can rent a brand new DA40 with G1000, (XM satellite weather, XM satellite Radio, Traffic info,) in America for half the price of a dodgey old Warrior in the UK with half the avionics missing.....
I own a quater of a steam driven plane in the UK, but all the avionics work, and it only costs me £40 per hour to fly; which is about £100 per hour less than the dodgey old warrior with half the avionics missing that the local flying club likes to rent me, which has similar or worse performance than my plane.
Given the choice between renting a new Glass cockpit TwinStar or old UK Warrior, I know which I'd rather fly.
