With all these issues is it not worth sticking with the mk5?
The mk5 , has its own issues aswell , 12.000 miles on mine , cam belt, water pump, tensioner's , pullys all needed replacing, then the coil packs, alarm system kept goin off, then the dreaded rattles!! All done under warrenty thanks FOOKs . At the end of the day they are cars and they go wrong, thats why i dont keep then long 2yrs max , then get a new one therefor I allways have a warrenty to fall back on. Not in into modding value my warrenty to much.
No doubt the mk6 will have its own problems too, but the car is still a great car to own & drive , and will always have one any day over the other crap that's out there. Enjoy Steve
