There was a thread on here a few weeks saying about how expensive PCP is compared to a cheap bank loan. Might be worth crunching the numbers and looking at drivethedeal.com to get an idea how much you could buy the car outright for and have no worries about mileage or ballon payments!
Its swings and roundabouts though...
Borrow £35k at 2% from the bank, you are repaying the entire £35k monthly - much higher monthlies.
Borrow £35k at 3.6% on a PCP from VWFS, you are repaying the loan the capital on £35k minus the GFV.
The only way the bank loan makes any sense is if you can extend the term to longer than 4 years and have an option to repay early (ie you want to change your car) without paying the interest that would have been paid over the full term of the loan.
With the bank loan sure you aren't being hit directly with a mileage charge, but you are effectively because the depreciation (due to mileage) is yours when you come to sell the vehicle. A vehicle with 90k miles on it after 3 years is still worth less than one with 60k...
PCP works for most people because the numbers are all predictable. What you have on the paperwork is the worst case scenario.
If you go for a "cheaper" way, you are taking all of that risk yourself. For most people they are happy to have a controllable budget and derisked.
There's no such thing as a free lunch...
