Got a phone call from the dealer at 9 o'clock this morning, my car is on it's way

Salesman said it's due in on Wednesday, when ill be able to go down and have a look over it, assuming everything is ok, they'll do the pre-delivery stuff and i should have it for Thursday afternoon or Friday morning. They've got another 7 cars turning up on the same transporter.
One thing the salesman mentioned on the phone was that it didn't get the winter pack
I decided to add this about 5 or 6 weeks after i placed the initial order on the 29th Oct, which working on an expected 14 week wait would still have been in plenty time but for what ever reason VW must have got their finger out on the run up to Christmas and it was too late.
I spoke to salesman a few times after i ordered the car and after i added the winter pack to see if he had any news but he had nothing through about build dates or expected delivery until he got a call this morning to say the car was on it's way!
It also appears the car has been fitted with parking sensors, even though i never asked for them

If they are indeed fitted they're not going to cost me anything but it's a little annoying as i didnt want them, granted they are pretty discreet but still... I dont know if i could or would even want to reject the car because of this, more than likely they would offer to fit a new bumper and switch the beeper off?
I think i'm probably best to use it as a bargaining point and see how much i can get off the price of the car, they might be quite handy if the Mrs borrows it
