Porsche depreciation can be rather savage.
I was comparing numbers for a lease on 2010 Cayenne GTS v. 2010 BMW BMW 5GT with TT V8 (in its 1st model year).
Same cap cost; same mileage allowance; same length of contract.
Neither party disclosed the money factor, though I don't reckon it differs wildly.
Anyhow, by my calculation the Porsche will end up costing - gasp - $17K more !
That would be without BMW "free" maintenance factored in, btw.
As far as Panamera goes, the extrerior is fairly tolerable in real life.
