Good post.
So i've just worked out two values... The first - i've worked out how much i've lost in depreciation on cars over the last 7 years. I've only ever had non-new cars (newest was 4 years old, but the average age of my cars is about 7 years old).
During this time, i've lost a totoal of £14000 in depreciation, or £2k per year.
Comparing the price of the SLK on PCP, a £1500 deposit + 23x £250 = £7250, or £3625 a year - so i'd be losing 80% more than i have done in the past on depreciation. Not good - although i would be driving a brand spanking new car for the first time ever.
However - looking on parkers at the previous gen SLK, price new vs 2yrs old for the cheapest model in the range (and therefore lowest depreciation) - they lose £11k over 2 years (not including any interest on finance i'd have to pay!) - which is a damn site more than the £7250 it would cost me to own via PCP. Okay this isnt a totally fair test seeing as the 2011 SLK is at the end of the model iteration, but it's as good a comparison as i've got.

So based on the above... financially i'd be better off sticking with old cars as i've always done - obviously. However over a 2 year period, PCP works out cheaper than ownership, as far as i can see, and doesnt leave me with the overhead of trying to to pay a £35k loan.
Don't forget to add any loan repayments on your old car figures and maintenance costs. If you included these e.g the £180 per month I pay off my loan plus the usual expense that comes with buying a used car i.e they're never perfect examples.
