And the VW Golf is MUCH smaller than YOUR Cadillac! 
I wouldn’t have bought it but I needed a “luxury” vehicle to qualify for a limousine permit, in order to be able to conduct tours the way that works best for me. It turned out to be a great move, since I was able to raise my prices. It’s been far more profitable than my previous vans, it has AWD so I can go anywhere in the winter, and my passengers love the heated leather seats.
I had to drive around Washington and Oregon for a week to find an Escalade ESV in my price range that could pass my detail inspection, my drive test, and an inspection by an independent mechanic. The difference between Escalades, Tahoes, and Suburbans is that Cadillac owners tend to have them serviced on schedule at dealers, so service records are available. They also baby their cars more. A pre-owned Caddie turns out to be a good deal. 
That’s a monster next to my little caddy lol
