Two Mercedes here 1967 250SL and the E500, my problem extends to having multiple motorcycles and fishing boats. In Florida you pay for the registration taxes on your birthday. Every birthday reminds me I have too many "toys" when I go through all of the registrations (truck, 2 cars, 2 motos, 2 boats 2 trailers they even get me for a canoe because I have an engine on it).
All I really need is my work truck, Street legal dirt-bike, my 250SL and multiple surfboards to keep me happy...boats, better to have a friend with a boat than to own one! The E500 is nice when I need more than two seats.
