Registrations are down pretty much across the board in passenger cars (-6.83%) , light commercial ( -1.3%) and heavy commercial sectors (-9.9% rigid, -4.1% artics, -5.6% Bus and Coach)

There are a couple of manufacturers who are showing an increase in 2018 vs 2017 - McLaren, Volvo, Mitsubishi, but they are a rare beast.

I suspect that JLR are only at the front end of a bit of an industry clear out.
