Spie is at the top of the car game - his budget is large enough to mean that he can afford a brand new example of any car he choses to indulge in and the depreciation is a non issue. I won't say he's lucky because it isn't luck that got him there, but he's certainly the exception and not the norm.
For everyone else, the £20k that would buy that brand new Golf diesel buys a better used Audi and the £40k that would buy that new Audi TT buys a better used Porsche and so on and so forth.
