I currently have a W203 C220CDi AG estate on a 51 plate, really like it but I also have 2 small boys so there is not room for an extra person. I want a larger car and was thinking about a ML / GL / X5 / Toerag etc. I really like the GL and would prefer to stick to Mercedes but is it massive but with the 7 seats it would be perfect and the rarity is appealing. The road tax is high on all of the choices so I have seen a GL 420 with the V8 Diesel which would make a very fast car ant they all seem loaded with options which is a good thing. What are peoples real world experiences of running these (ML or GL), I have an excellent local MB specialist for servicing so not particularly worried about those costs as they are fixed prices. This would be my ideal choice http://www.autotrader.co.uk/classif...ch/true/radius/1500/postcode/tq12lr?logcode=p Opinions????
