For classic cars, I've really started to look at these, not sure why but I really like the look of them....

I could never decide between a W116 SEL, a W126 SEL or a W140 SEL, still can't
so have yet to buy one...
One day I will own one of these though...

Preferably in dark blue metallic or gunmetal 
I confess I know little about the Wxxx numbers of Merc's

Just something about that link i posted, the coupes, they just look retro cool to me. Well proportioned.
Been browsing forums, apparently like my 2.2, you don't need a jack or stands for oil changes, they were built then when mercs we mercs and everything was over-engineered.
So a Coupe with plenty of poke, easy DIY work, parts apparently even from Merc are well priced. Bullet proof engines
