Had my Mk 4.5 just over a year now. Only done 8500 miles, overall pleased. Is well screwed together, the SEL seems to be the sweet spot in terms of kit, only miss not having a reversing camera, was a stock car so can’t complain on that front. We ran a couple of MK3’s and this is a genuine step up. The infotainment system is ok, mine has had a couple of minor glitches, but nothing major. The a/c and climate control, is fairly straightforward I pretty much leave it on auto. Only minor complaint is the heated front screen control is a little hard to fine. I switch off the lane assist each time I drive, but it’s a couple of clicks so no real hassle. Good motorway car, took us all away down through Germany in the summer and for a 1.5 55mpg is really good.
