Very good question and one to take note of
(don't trust them!), I almost got stung big time and I only waited 3 months for mine!
They gave me a price for my S3 and said the difference between what we offer now and the settlement figure for your car will stay the same, as the price of the car comes down in line with the PCP/finance on the car.
Example px today £21,000 you owe £21,200 then in 3 month px £20,000 you owe £20,200 both showing £200 gap. They said "The S cars don't drop by a lot, so you will probably find that you're in a better position come change over day".
So I asked what if the price bombs out on the S3's between now and then? They replied with "I very much doubt it on the S cars, but if something drastic happens and the price dropped a lot, then we'd have to look at the deal again"!!!
As it turned out the price of the S3's did bomb out............... I'll try to find my old post.......here it is:
As you can see from 19th Aug to 23rd Sept it dropped by £20, then 8 days later it dropped by £730 and then 6 days later a further £1,010
so £1,740 in 2 weeks! It hadn't dropped by that much since January!!!
Audi had been looking at
£21,000 px which I was happy with, as that was around what I owed 2.5 years into a 4 year pcp, but they then dropped to £19,000 closer the time of delivery! Luckily I combated that loss by doing 2 things:
1) I paid the finance off on the S3 as soon as I ordered the A5
2) I ended up selling the S3 to a sports car specialist for £20,500
By doing that I saved 3 months worth of interest whilst the A5 was on order and I got the last payment I'd made back, so that added to the money I got for the car took me to around
£21,200
*Make sure that any quote on a px that is a few months away is rock solid and not due to change. Let them work out any potential future loss and make them agree to stick to it....in writing!
*Tell them to keep the px deal and the new car deal separate, so you know exactly what you are getting for your old car and what you are paying for the new car.
*Remember you can always sell your car to someone else closer the time
(unless agreed in writing), when I went to sign the paperwork on the A5 they said we need to look at the S3 again, I said "Why, you're not having it", their faces were a picture
I then said "I'd said from the start that I wanted to keep both deals separate from each other as I may sell it privately"
