Some very nice cars, the title is sort of misleading as many of them already gained value.
One insider tip's missing though, the E50 / E55 AMG (W210 series), should replace the E63 in my opinion. Great engine without major flaws (some rust issues though, but let's call it natural selection
) and it's still possible to find some good cars for less than 10.000 €, don't know how the UK prices are.
