The Crossfire roadster is my regular commuter vehicle due to its good reliability and fuel economy. It gets used when don't need too much luggage capacity. Gets about 8-10 K miles per year
The Mondial 8 gets used on dry days when larger luggage capacity is needed, it is below freezing so top on XF won't go down, or I feel like it and I will be parking it in secure areas. Gets 3-4 k miles per year
The V70 XC (3-4 k miles per year) or Compass (10-12k miles per year) come out when need larger interior carrying capacity or moderate adverse weather. Compass is wife's normal commuter vehicle.
Deep snow, heavy hauling or for towing the Ram 2500 4x4 comes out--not used when not needed due to the V-10s thirst for fuel. Ram gets 3-4 k miles per year.
Berone X 1/9 gets out on some nice days --2-4 k miles per year.
The 60s Newport Convertibles are garage queens awaiting restoration with a few hundred miles a year when I get time after I retire.
The Italians and the Newports do not go out in wet or when salt on the roads as they are quite subject to the rust monster. The Italians also tend to be "tempermental" maintenance hogs.
