Woah this is an interesting discussion !
SOme very blunt but realistic replies here
Im into my 10years + cars so ill waffle on abit here . hopefully makes sense
But I think some of these cars, as great as they are or were, need to drop in price and I think that time has actually come.
Standard non 'top of the range' cars are now keeping up with the sl55/m6/m5/cayenne turbo
For example m135 is around 12-14k with similar miles to an SL55/the above cars, but will be about 10 years newer, better fuel ecomony, better tax class sometimes and generally less to go wrong. its sort of a no brainer. As much as I like those older cars It just isnt worth it anymore
mk1 cayenne turbo 5.3 seconds to 60 - great? £10k ish or £16k for the 957 facelift... 10mpg £600 tax
or buy a bmw x3 or x4 35d (yes deisel) 0-60 n 5.3 i believe probably around the same price at the cayenne money
I know were not talking about cayenne turbo / m5 / m6 but these are all in the same category of old superfast cars which are priced high for those reasons ... but are they REALLY worth it?
plus the blob twin eye mercedes generation face is really far down the line now. I like them im a w203 fanboy but to the average car guy they are really old. Mercs have so manyfaces since then its crazy.
Answer is then to facelift the r230 and it will give it another 5 years of desirabilty as the 2009 face is similar to the w204 face / c63 which is still hanging in there (I think)
sl55 will be a classic. well all look back at these threads and kick ourselves. 10k isnt bad for that sort of power in a v8.
