An absolute no brainier - get it done today. I bought mine from new at the end of 2018, possibly the best car I’ve ever owned.
Economy is great - drive reasonably gently on a long run and 40+mpg is easy
Build quality - top notch
Equipment level - as standard, struggle to think what else you would want
Service costs - probably no more than what you are paying now
DSG - brilliant
Looks - Indium grey is a great colour, makes the red trim pop out ( I’m biased)
Fun factor - where roads permit, plant the right foot, feel the front end lift a little and watch the horizon rush towards you😎😄
