Hi mate
I bought a V5 about 4 or 5 yrs back and loved it... Admittedly, I have never driven a Turbo or any of the other VW's that folk tend to prefer, but I did love it. The only reason I sold it was cos I needed to do more work miles and the VW was simply not cost effective.
However, I am now working form home and finding myself topping a massive 1000 annual miles. So I bought another... It to is spotless and I got it for £2650 on a 52 plate with 59k on the clock...
I drove it back form Birmingham, where I picked it up, and averaged about 31mpg, which I thought was pretty good. Around town though I dont expect much more than mid 20's at best... Yes it did come with CD changer, in the boot, although I know some come with them in the dash...
Hope this helps
