Ordered my car on the 5th of July so not happy about this.
Going to check it again next week, and if it still says December, im going to call Vauxhall to see what they say, then speak to my dealer as I told them the 24-27th of October was the latest I can wait for it otherwise it will start to affect my job.
I asked vauxhall customer services, via Twitter if they could update me as the tracker has changed for over a month. They said its at the plant but can provide a better update Middle of next week. Tracker arrival date still says 17th October. Hope it's not December or I'll cancel.
