Congratulations. You have chosen one of the most complete cars of all time.
Mine has had no faults in 3 years/36,000 miles. It does not irritate me with any quirkyness, it's fast, stable, easy to drive, and a useful size. It's good on fuel consumption and servicing is actually quite reasonable. If also has class way beyond the price tag and above all is great fun to drive.
I only have three slight grumbles about the design; the reversing light is a bit dim, the loading bay is not flat with the seats down and the standard radio lacks clarity.
Buy a Mk5 GTI (in whatever petrol guise you choose) and you will go from this

to this

in no time.
