I'm hoping to test drive the Mk6 then if I like it, trade my MK5 in for it next summer when it comes out. Reasons would be, although I love my black Mk5, its hard to keep clean, gets darn hot in the summer making it hard to clean. I'd choose silver or red next time. Probably red. I would like more power, and 4wd plus good fuel ecomony would be a "No Brainer".
Better looking higher quality inside, quieter cruising, adaptive suspension, better sound system, etc etc.
Plus the "feel" and smell of having a new car, it Rocks!
Adding to that, the MK5 would lose value quick with a new model out.
