My GTI is also sat at the dealer as of Friday and I've decided to wait until 1st March for a couple of reasons:
1. New Reg - my 1st new car and I always envy people who collect their new cars on 1st day of new registration
2. I'm hoping the worst of the weather will be out the way, although it did snow in March/April last year!
3. It's my birthday on 28th Feb and my wife has planned a nice weekend away for us, all starting with picking up the car on Sat 1st March and going away in it.
The value isn't as important to me, but I do think it will make a difference.
I don't want to rain on what should be a really great day for you, but I hope your dealer hasn't got many cars going out on March 1st.
Think about the logistics of it. If they have a lot of cars going out on march 1st
1: The valet might have been done a few days prior to pick up so it might not be as clean as you thought or hoped.
2: The pressure to get a lot of cars ready might lead to a few corners being cut.
3: The salesman will be under pressure to get as many hand overs done so denying you the standard of service you deserve in the rush to get to the next customer.
A friend of mine works in the trade and he said to me once. Never pick up a new car on new reg day for the reasons mentioned above.
As I said I don't want to put you off but wanted to offer a different perspective of a March 1st pick up.
