Auto erratic

Another clueless use of the bastardised form from a car reviewer, as Auto Express asks of some new hatchback:
Flagship version of SEAT's Ibiza Cupra features blacked-out grille, but is it all mouth and no trousers?
Again, this would have been fine with the proper version of the phrase - the flash exterior is there (the grill, like fancy trousers), but the question's whether it has the performance to back up its appearance.
