So he became such an enthusiast by only ever owning that car?

Yea, because if you never switch to better tires to improve your driving abilities, or switch to a better flowing air filter, or adjust the car to support your driving style, then you probably aren't using the Enzo to pursue your interest in cars or driving. Same applies for the muscle car. You bought/built a show car. Being able to drive what you own and being able to improve on is part of being a car enthusiast. Pursuing improvement in driving/performance of the machine and yourself.
