I get the question. I had an Aggie Band buddy whose parents split up our Junior/Senior year. By our Zip year, the drama he went through was that each parent wanted to buy him a car but neither parent wanted to pay for college. The split-up was initiated by the mom because she thought the dad was a loser. The mom went off the rails when the dad found a new woman who was younger, nicer, much prettier and remarried within a year. By our 5th year, the guy started smoking weed pretty often. 3 years after that he was a major pothead. He's reformed and teaches Elementary School now. Those couple of years were nuts though.
As a parent of college aged kids now, I see how easy it is to get a car loan. Getting school loans takes more work so I see why one parent would be like - hey, I spent $20K on a car, you should spend $20K on college. Or, insert your own numbers here.
