They're old luxury brand cars with expensive parts. They require more frequent maintenance that many second-hand owners have neglected due to cost or ignorance during their two to three decades on our roads. Their gaskets, seals, wires, and hoses are made from the same rubbers and plastics as all other makes that will degrade over time and many of these original pieces are reaching the end of their useful life cycle. These aren't cars intended for casual drivers or non-enthusiasts and they ultimately are a labor of love for their owners and curators.
