And, even with 3, say 10 year old, cars, you are into them for less than 1 new car, you lose less money than you do on 1 new car, and you have three vehicles for versatility and backup. The "two is one and one is none" concept. With one car, even a warranty repair might leave you car-less unless they provide a rental. With 3 cars, you can have 2 down for maintenance and still have a vehicle to drive.
And 3, $10,000 cars is less money in every respect than 1 $40,000 brand new car, even if you have higher maintenance costs.
