GFV is based on real value - it's proportionately low as it is a cautious measure of worth but there's no way a 45% GFV is going to equate to 60% real 3 year value.The manufacturers get closer to reality so they can get the monthly payments down on PCP as much as they can to lure the customers in. I'd probably expect 51% p/x on a car with GFV of 46%. I'd also expect a realistic 61% on one with GFV of 56%. With figures like that in mind , the 120d/123d/125d is going to cost me £3k more to run in depreciation. There are cars out there i'd forgo that money to get over the GTD (maybe next gen Audi TT). I wouldn't rather have the BMW on an even standing with the GTD, let alone £3k more.
I do consider more than the GTD, but buying new it seems by far the best value of it's peers all things considered. It's good value new, but poor value as a second hand car - I don't want to be paying 75-80% of RRP for a 3 year old car. With that small differential i'd always buy new. If I had only £15k to spend i'd consider the 3 year old BMW option, but i'd be more likely to pick the Alfa Giulietta for probably 50% RRP on the forecourt and still have the reassurance of 2 years warranty left of the 5 year warranty.
When it comes to my money, I like to spend it wisely and put a lot of consideration into a £26k purchase.
I'll wave at you in my rear view mirror in the snow, but the other 98% of the time, you've got me!
