Not really old by those standards but I’ve got a B6 on an ’07 plate with about 85,000 miles. It’s a Tdi and I get about 43 mpg regularly and can get this up into the 50s on a long run if I’m careful. Can easily get three people and three bikes inside and have had two adults/two kids and four bikes inside once.
It has been 100% reliable, unlike the A4 I had before. It’s bigger than an A4, costs much less and just as well built. The only fault has been the usual uneven rear tyre wear and noise, which I don’t expect VW will have tackled in the B7, which I’m expecting to be delivered in a month or two.This one will come with a heated windscreen, which excites me because I have wasted so much of my life scraping ice off my windows!
