How do you get to 1100?
48 months, no deposit and 30k miles a year only gets to 758 a month on the VW calculator.
10k miles and a 5k deposit and you drop to 517.
Easy- I just tried.
Use their finance calculator on an R (base R, no options, not that you can do options in their calculator)... put 30k mileage, put 24 months and a 500 quid deposit.
23 monthly payments of £1,117.93
You are paying £23439 of depreciation plus interest 5.6% APR.... there's no getting away from the depreciation... its only worth £18751 after that sort of battering.
BTW only put the mileage in if you intend to hand the car back.... handing the car back is a pretty dumb thing to do on PCP anyway - lease if you want to do that, its better and cheaper. If you don't intend to hand it back, but want to buy it (and then sell it yourself) put in 10k as the mileage.... it helps a bit - £925 a month, becuause the GFV is higher - 23k
The basic problem with a short term is that you are hit with the big part of the depreciation right up front. By having a longer term you spread the initial depreciation over a much longer period, meaning cheaper monthlies.
Lastly, thats not going to be just VW - any new 42k car you want to PCP for 2 years will be like this.
