Cessna 150 unscheduled spares cost this year over 100 hours £0!!!!!!!!!!
Rover 75 over 7500 miles new clutch £500, new diesel lift pump £400, new tyre £50, new bearings at top of front suspension £250, new battery £50.
Still the insurance was about a quarter and no hangarage to pay for. Also I'm not going to have a large amount of money extorted for an ARC every year.
However to the question my 150 is certainly more reliable than my Rover!!!!!!!!!!!!!!!!!
