The horse thing is even worse when you realise Musk was trying to offload the horses because they had relatively little value and it was costing him more to keep the horse than it was worth. He smushed a bunch of ranches together and he purchased a few of them lock, stock and barrel to get the deal done, this included some low value horses that he would have been stuck with costing him money.
Cars have also gotten much bigger, generally speaking more reliable, and stuffed with extra technology, some of which makes the car safer than before. Little of that technology is really optional now in the EU but still adds to the price.
A cirrent polo is the same size as a mark two golf, a three series is same size as an old face series. Most could downsize and not notice.
New cars are purchased on the monthly cost than anything else where I am, with a balloon for the final payment. Manufacturers make money again on the same car at the second sale but can only do so if they protect the resale price, which means ever increasing sales prices.
