Though I would share my approach to my cars. I have 4 cars (56' 190SL, 91' Twin Turbo 300ZX, 2006 F430,2015 Hyundia Sonata).
The 190 is driven every Sat or Sun morning with the top down through out the year. The only time the rag top comes up is when it is too hot(over 74f) or I get caught in the rain.
The 91 TT Z becomes the daily driver Fri-Sun. A poor man's super car
The f430 leaves the garage early Sat/Sun morning and goes for a 50-80 mile drive. Last Sunday I scraped the bumper driving aggressively down Page Mill Road. Back in the garage by 8-8:30am.
2015 Sonata - The daily driver. The car that hauls stuff from Home Depot.
If I were to get another car, some how it has to fit a time slot.
