Robert, you will trade your VW before it is old enough or has high enough miles to be a problem. I will have this LS430 well past that. So neither of us are wrong.
I will have this Touareg an easy 7 to 10 years, I have a full 2 year warranty (including all service of oil changes and fluids) I can then buy an additional 2 years of full warranty (excluding oil changes ect) for an additional 360 Euro a year. After that VW will sell me an another 3 year limited warranty. I will never accumulate that many kilometers on the diesel to matter and the body comes with a 12 year warranty for rust. Bottom line is I love the looks, the interior and driving this car more than any car I have ever driven.
Besides, with our latest addition here, my car budget has just gotten directed in another direction for sometime to come.
