Welcome AnDrew

Get a late model 7.5 as they’re well equipped out of the box and the interior feels more cockpit like after being used to BMW’s. Everything on them just
works.
I had 5 mk7 models but am now 25 months into mk8 ownership.
Tech gremlins are guaranteed but the severity is pot luck. They’re still under warranty so not a huge worry, just really annoying at times. My car will be faultless for days on end and then I’ll get a few days where the bongs are horrendous. Trouble is they’re so inconsistent booking into a dealer would be a lottery as to whether I could replicate the issues to demonstrate.
As said, the steering wheel has been blamed for a lot of the issues so when test driving I’d recommend turning the wheel lock to lock and do some low speed manoeuvring that requires lots of steering lock to see if the car you’re testing has that particular issue.
Also low speed suspension knocks are common. Mine does a bit of low volume squeaking at very low speed over bumps at certain temperatures but not annoying enough to book it in to a dealer. Again, it’s an intermittent thing so hard to trace where it’s coming from. Could be door rubbers, suspension gaiters, top mounts etc.
I’m bang on mid ‘50’s and drive a Clubsport.
The spoiler isn’t Honda style ‘in yer face’, it’s quite subtle.
Old guys drive Porsches and Ferraris - who cares what people think?!! Let the neighbours know you’ve still got gas in your tank by not driving something boring. And that’s coming from me who is the world’s most boring person.
