I don't subscribe to the "They don't make them like they used to" stuff.
I'm going to show my age now but I remember as a child sitting in the back and being able to see the road go by, oh and paddling on water when ever it rained
thankfully, yes they don't make them like that!
There are some exceptions of course, such as the Mercedes W124 E Class of the early 90's. Probably one of the last cars designed and built without the interference of accountants.
New cars, are by and large better than the previous generation. They're not deliberately built to fail at 4, 7 or 10 years. But dealers and manufactures need to churn cars. They're not really interested in your 10 year old car. Again an exception, I have a 26 year old Mercedes. Just about anything is available, even if it comes from Germany it's only a 3 day wait.
So that's why forums like this, clever individuals and smart independent specialists can keep your UP on the road for many years to come. Don't take too much notice of the manufactures service schedules (designed to look like cheap motoring for the first 4 years) and I'd expect 200k miles and 15 years before it became uneconomic. Ignoring any government legislation that may appear of course.
