I've never had the money to do it but know several folk over in the Audi forum have done it successfully.
The fact your salesman told you you couldn't settle it within the first 3 months is blatant lies.
If you are worried you could always take out the PCP to get dealer contribution and cheap insurance and possibly a better discount then rather than cancel it in the first 14 days, make a very large payment within the first 14 days say £100 less than the full finance. Then settle the remaining finance of £100 after the 14 days and that way the interest would be minimal and they can't claim you never took out the finance.
Sneaky? Yes but so are so many salesmens tactics if you ask me. Not all of them though.
I'm almost certain that you can't do the all-but £100 payment you propose. VWFS proposed a monthly plan and you are either accepting it by making the payments as per schedule (and settling the balance in full at any time after the commencement of the agreement, including any early payment penalties such as 2 months interest that they've charged me in the past). VWFS requires you to have at least 70% of the RRP under finance. If you buy a £30k car with a £3k discount, the most deposit you can put down is £6k to bring you down to a minimum £21k financed (70% of the £30k).
You can try your luck for very minimal outlay -The interest you'll be charged within that 14 day window of cancellation on a £21k sum will likely be in the region of £4 a day 1/365 of 7% of £21k.
Worst case you're £4 or £8 down for a few days, against the potential of getting all those incentives (if VW haven't battened down the hatches in small-print).
