Kim, the clock on your allowance is already ticking, by waiting until October, and a possibly long delay before delivery, will eat into that time.
Awards can be reviewed at any time, normally 6 months before the award ends, there was some wriggle room over 2020 because of covid. Please don’t get seduced by a shiny new car, car buying is emotive. In my case I don’t do many miles these days, I and don’t think, I will be staying on the scheme as its not worth it to me, the APs are too high for me, and too many brands are making you pay for extras in packs. My current car a bmw gran coupe, was a close call to staying on or staying, its purchase price was £26k, my old x1 was over £40k, ap was low last September 2020, with dealer discounts, but now its priced itself to high, even the leather interior, is an £1150 extra! As has been said, it’s how you value convenience of the scheme, in my case, I shall use the allowance to fund my own car. I will replace my 2004 mb clk, which is still a head turner, with a cls or 2 seater convertible, my partners alfa mito 2009 is in superb condition, a fun drive, and costs are minimal, just mot and annual service, and the odd part. I tend to put new boots on all round at once, when I offers come up at kwick fit or costco. The allowance easily covers maintenence costs on these cars.
