It has to be said that the items in Snoopy's list don't occur all that often. I would have to add road noise caused by saw tooth type rear tyre wear on 18" wheels and certain makes of tyres. Bridgestones and Dunlops seemingly being the worst.
The Mk6 Golf in any shape or form is a bloody good car, and whilst I can't comment on a GTI, from what I can gather they'll do mid 30's mpg, so if that is acceptable to you, I don't see any reason why one shouldn't make a very good daily companion.
