VW Passat Alltrack with high spec (auto, sat nav, leather, etc). £32k to buy but there was a lease deal at £119.99 per month for 2 years.
Total cost £3,120 over 2 years
I really struggle to believe that it's possible to own a 32K car for the first two years of it's life and only pay on average £130 per month.
Or, to look through the other end of the telescope, If it's really possible to get it for £130 a month, the I suspect it's not really a 32K car.
Even if it's true, forget cherry-picked examples, take the first 20 different random examples of cars that people nominate (i.e. not chosen because there's some mad special finance deal) and how many of the 20 will be cheaper via PCP? I suspect none.
In fact, if the PCP terms are available on-line, someone find a list of the top 10 most popular cars somewhere and see how many of them can be had cheaper on PCP. The rules of the game are you are not allowed to change the model or options in any way to get a better deal, you have to get prices on a predetermined car.
Manufacturers do sometimes need to get rid of models that are flops/overstocked, and selling them via PCP could be a way of not devaluing the brand by making it obvious they are giving them a way. If that were the case in the Passat example, what it means is that it's not really a 32K car, even though that may be the cash price.
