If you drive just right, like the experts say it will last 1,000,000 miles... driving it like you do, it will last 900,000 miles.... get my point. Get the car you like and drive it as YOU NEED to serve your needs.... These are not garage queens, driven only on Sunday. Use it, enjoy it and stop reading too much from the experts.
Clearly the car is ideal for open road, gets better millage at constant freeway speed.... blah blah blah... who cares. You can't change the traffic.
PS there is no crystal ball to tell you when to get rid of a car. This has been an age old debate. If you are going for return on investment, you buy a late model high quality USED car and drive it into the ground... 10 years, 20 years.... I did that with both my Acura Legends and THEY WERE STILL going strong.... Some people buy a new car every few years or lease cars. If money is no object, then you would sell your car (VW) every 3 years or 36,000 miles (ie in warranty) to have low risk. There is NO TELLING when something BIG will let loose. Being VW and "German" they cost more to own than a Hyundai, Kia, Ford... etc.
PSS when an internet expert says Blah blah this will happen if you do this..... read for proof, data, evidence, facts.... most of it is opinion. Even the "testimonials" and "it happened to me" and "a friend of mine..." have very low credibility or just not relevant, too small of a sample. Don't get me wrong, I have opinions I like sharing, and like a broken analog clock, I am right twice a day.
