I was surprised to learn that most supercars regardless of brand never make it to 100k miles. The Quality and QA testing just isn't there, with so many parts made of cheap plastic and even the car bodies getting severed in half in minor car accidents. And fixing even the simplest things like replacing most parts requires dealer sold OEM parts, which instead of costing a few hundred dollars cost 7,000 dollars. You would think if you're going to spend $200,000 on an Italian super car, you should get a high quality car that will last longer than a cheap Japanese economy car costing 1/10 the price. But the opposite is true. So if I could ever afford to buy a super car, it would be an Acura NSX, so that at least you would get Honda's reliablility instead of some Italian supercar maker's reliability. If you google: What is the cost of an oil change for a Bugatti Veyron, the answer is $21,000 for the oil change. For the price of that oil change, you could buy a new Honda Civic or Toyota Corllla and get the whole car. Even if I were a billionaire, I think I'd pay my local mechanic $30 for his labor and give him 5 quart jug(s) of synthetic oil and Fram Ultra oil filter bought at Walmart.
It's also interesting to note that in the latest Consumer Reports Magazine, Mercedes Benz is dead last of all car model brands in reliability.
So with Mercedes, you pay astronical prices for low quality, little to no quality assurance testing, with astronomical parts prices.
I suspect this is intentional, as Mercedes can lessen their cost in making a new car (both parts, research, and Quality assurance) to the lowest cost to Mercedes it could possibly be to build it, and then to sell the car to consumers at astronomical prices based on some misplaced and outdated reputation of quality, and then to allow dealers to astronomically price gouge on the parts and the servicing. So maximum profit for Mercedes and their dealers, and minimum quality to the consumer. That is really a shame, as Mercedes could have taken the high road and actually produced cars that can go to 400k miles like they used to in the 1980's and 1990's.
Consumer reports says Toyota/Lexus remain the top 2 most reliable car brands for many years running.
But to me, Toyota's bland styling and handling are blockers, so I prefer Honda's myself as they are fun to drive and have nimble handling.
