While that clunker you see rattling down the road or highway probably isn't worth much even if it's thirty or forty years old, some automobiles are quite valuable and may require that their owners employ a Suffolk County classic car storage option to keep the vehicle safe. The most valuable classic cars include a 1931 Bugatti Royale Kellner Coupe which, adjusted for inflation, is worth over seventeen million dollars. A 1929 Mercedes-Benz sold for almost eight million dollars and was considered a sports car in its day. Only thirty-three cars of this type were ever built and only a handful has survived.
