The wording of the ad may be a bit off but class action suits in the USA have secured substantial amounts of compensation where real world fuel consumption did not match the makers claimed figures' I think Hyundai were one of the main culprits.
That's as maybe, Dave, but I'd be very surprised if anyone got compensation because they knew someone who owned a diesel.
I think it was mainly the VW group that was the main culprit in the US dieselgate. As far as I know there has been no action against Hyundai anywhere - yet
I've wondered why the BBC uses that greeting and "Good afternoon" would be appropriate only for those watching in the UK and some other countries but not for the rest of the world.
