hhm is say that a merc estate is the most practable car in the world, for sure...such great build quality and space and luxury on four wheels is hard to find without the silver arrow, or star more appropriatly...
the 123 is such a brilliant car, however the dated interior can seem to old, even in comparison to the 124 interior, which is so ergonomical and well planned out...i drive a 200te, white with cloth interior, manual windows...very basic and the interior is never-failing...all the dials and buttons not only look great but still feel great to use...ive never been in a 123 but im sure it is the same...however i reffer the angular designs of the 124 interiors...
the mercedes of the later nineties and earlier noughties got a much more reounded and less angular intrioir, i find this to be less ergonomical however, the buttins are still very solid, we had two etates asfmaily cars, however there is always the issue that the car, (the 210 model was it??) was built for the american market, mercedes being owned by gm(i think at the time) lost its fundamental aims of absolute build quality...
the later e class models, form 2003/2002 onwards were much better, however some people have known to have 'friday cars'(the odd car that is full of problems)...however our family 320cdi, bought in 2005, now with 100000 miles on it still goes like new, very solid...friends 2004 320 cdi is full of problems, and have refused to use it for a year, looking to sell it however depreciation has avoided it...
Ive seen pictures of japanese market w124 E60 amg's...this, to would be the best merc if i could afford it/get insurance...fast, with the best design, and excellent build quality..
ive even seen w140(nineties s-class) adapted into estate, using an old ford estate boot top...looks ok but of course very rare and i imagine maybe seriously impeeded quality...
have a look on youtube for the 'Fifth Gears w124 estate durability test' to see just how literally bomb-proof mercs can be...truly awesome...
