I drive a lot of miles per year and assuming I can afford to buy more than one car does it make more sense to spread out mileage over 2 cars or just put more miles on one car?

Answer 1

Assuming you can afford a second, that might make sense, depending on the condition of both cars, and depending on how much you're willing to spend on repairs. The decisiion comes to this, "Do I want to buy a second car, spend that money, and worry about insurance and repairs for two cars, or do I want to use one car and repair it?" It's your choice in the end.
