Have a good look at the rear window through the rear view mirror when moving at a good speed in the 172 Cup, sometimes it vibrates so much I swear its going to fall out! I may be a bit odd but I like these quirks though, some call it build quality issues but I call it character! Admittedly if I owned a full fat I would expect some luxury, but considering I paid for a car knowing it has thinner windows and "modified" sound deadening I can have no complaints.
