I suspect the under 30 and over 50 bias is more related to having kids to haul and needing a backseat with finances limiting going multiple vehicles. In my 20s I drove 2 seaters Fiat 124 Spyder and X 1/9--with 10 year old Fiats needed 2 so one would likely run to get to work , once kids came got a truck with a backseat and a station wagon Late 40s Went Mondial 8 for backseat for occasional teenager hauling once the they had driver's licenses went back to 2 seaters XF and Bertone X1/9 for more fuel efficient commuting etc while keeping the truck jeep and a station wagon for hauling and adverse weather.
