They already seem to be soft on newer cars. My mum's Fiat 500 passed MOT with both wheel bearings hanging out of it. Same with my wife's Mini - it passed with a balljoint hanging out of it. Yet if I bring a 2004 Mini over it gets slaughtered.
Try bringing a Civic! Balmoral had it near an hour, revving the nuts off it probably trying to get me for noise (just a manifold and Milltek), obviously going over it with a fine-tooth comb, with at least 5 people I counted arriving after me and leaving before me. Also came out with the airbag light on he said appeared after the test was done, I haven't seen it again since turning the ignition off after (that was in November), no fault codes. Got me for de-cat! Waited for the 21 day retest period to expire (wouldn't just let me book another full test), took it elsewhere and it was in and out in no time with a pass.
I've said before though, they probably see their fair share of scrap Civics not properly maintained. Minis are probably the same.
