Regular driving is the best preventive maintenance you can give any vehicle.
A friend of mine oversees a large local car collection. The vehicles range from the 1910s to the 1970s with heavy emphasis on the 1930s Classics, including a couple Duesenbergs.
Every single vehicle in the collection is subject to a 3 hour drive on local roads at least once a month. This keeps everything lubricated, the fuel system fresh, etc. It's quite amazing to see a 1934 Duesenberg or 1918 Cadillac driving through town in regular traffic.
Anyway, at a natrional show (either Hilton Head or Pebble Beach, I can't remember) the Duesenberg Town Car was competing against other Duesnebergs (they're in a class by themselves, of course). The presumptive winner was a roadster. After all, who doesn't like a two-seater over a stodgy , formal limousine?
The other owner didn't subject his vehicles to regular use and the roadster failed to start and run on the show field. The top prize went to the town car as a direct result of the opposition's lack of regular use.
