If you wanted to really use gas you could get the turbo charged
version. I don't know how many of those they sold.
We had one (turbo charged version) here on the field about 10 years
ago. The guy said he'd always wanted one, but only kept it about a
year. It was eating him out of house and home for gas and maintenance.
I don't know if it was due to that specific plane or it was a trait of
the breed.

Not just turbocharged... pressurized AND turbocharged!
