RickRoll It depends what you are buying. If you are going to a 10-year-old luxury Mercedes, then you can expect a world of hurt in repair bills, and hence a Lexus will be more expensive for a comparable car, because they are much cheaper to own.
You're wrong. I've always had Mercedes, and I have never had bad repair bills. My 14 year old one just passed its MOT first time and I live up a rutted off road track. I've had one which was still going strong at 250,000 miles and another at over 212,000 (I only sold them as I fancied a new car, and they are easy to sell second hand even with that milege). Obviously if you do things such as replacing brake pads and checking tyres are legal before you put it in, it helps. If you are more interested in resale value then you will pay the Mercedes garage to do everything, to keep the Mercedes service history. But tbh if you do some of your own repairs, the Mercedes garages can actually be very helpful about ordering very small not very expensive parts, especially if it is an older model and they are interested in it. Every single one has been very, very reliable, and not expensive to repair.
There is a whole world of classic Mercedes out there that are very popular and not too expensive to repair because they are looked after. Even cars which were quite ordinary 20 years ago have now gone up in price because Mercedes is one of the few makes that does last. Its also interesting that Mercedes and some other luxury German brands do consistently lead the market in styling innovations that can look a bit avant guarde when initially introduced but which tend to be copied by other manufacturers a couple of years later. e.g. round headlights, now square sloping headlights.
Its also way more env friendly to run an older car which is reasonably emissions efficient than buy a new car which will be scarp after 8-10 years.
Interestingly the Americans are much more worried about reliability - they buy luxury Hyundais, Hondas, Kias, and Toyotas, because they are so much better built than the German competition, but in this country the most important thing is the badge on the back.
Americans buy big inefficient cars because gas is cheap and they don't care about styling. I mean they also like Ford Explorers which have to be the most uncomfortable, bad to drive, cars ever built. I think you're trying very hard to sell Japanese cars but I've been a passenger in a couple of those and in no way does the comfort level compare to that of a Mercedes, particularly if you have a bad back.
