Delivery
That does seem a long time. My order was on the 15th November and dealer gave me delivery date of February 28th 19. However, when Vauxhall confirmed order they gave dealer 1st February 19. So it's wait and see who is the nearest. I know it took 4 to 5 months for my Mokka's but they were shipped from Korea.
Unreasonable, not sure as it's down to the Dealer to 'manage your expectations'. I'm in a similar position with an initial Dealer estimate of December delivery, but the computer said Feb 19 when order processed. It's now expected at Dealer 4th Jan (exactly 12 weeks from order), but I'm not holding my breath.
