Especially when you are an aircraft owner, never train emergency procedures, and are blissfully unaware of the true state that your airplane is in (you may have paid for just the paperwork and the bare necessities)...
None of the above is necessarily correct. Many private owners do their own maintenance, and practise for emergencies. If you aren't renting you can take the time to train, the insurance and hangarage are paid, so it's just the petrol. And if the weather goes sour nobody is yelling at you to get the aircraft back.
