Some PC brands, you'd be right. Nowadays, however, I find Macs last maybe 5 years before coming super-duper slow. Plus, if you get into the smallest accident, oops, you have to replace the whole car. You can't upgrade the engine, seats or anything either. Plus, oil & tires can only be replaced at Apple Stores or authorized dealerships, as Apple wouldn't make it self-serviceable.
I can't even check the transmission fluid in my own Ford Truck. How many of your cars have you done an engine swap on?
