2 drivers, 5 cars. Although my project car doesn't really count since it's been sitting and hasn't been driven for a few years now. But it does run and drive if I really needed it. So, 4 cars. I'm currently trying to drive the wheels off my old Accord. If/when it dies, I'll get rid of it and probably won't replace it and just drive the truck every day. But the car runs perfectly and shows no signs of dying any time soon. Don't want to sell it as it's hardly worth anything and it's more valuable to me as a practical and reliable car (and I just plain like the car). Plus, it's so ridiculously cheap to own it actually pays for itself in gas savings, even accounting for insurance and registration costs.
It's nice having extra cars so I can take my time on repairs. All of my cars are very reliable and don't often need repairs, but when they do, it's not uncommon to have it sitting in the garage taken apart for days, or sometimes even weeks at a time. I have very little free time these days, so I might get an hour of wrenching time one day, 15 minutes the following day, no time at all for the next 4 days, etc.
