2008-reg Diesel, Owner for 1 to 3 years

I've had no problems except windscreen washer container has no filter and has blocked twice!! to clean main dealer ł100!! indep ł48 still a lot of money because mercedes don't put in a simple filler filter. have made one myself. Fuel consumption is great after a volvo xc90. parts are expensive but it is a mercedes, it's not so much the parts as labour fitting. buy genuine parts and get a trusted garage to fit them. if in doubt get mercedes to check it out, it's still cheaper.

This car has only had 6 months use but is completely reliable so far. The economy is much improved on my previous mercedes b class and road fund license is free in the first year and then ł30 which is also a saving of ł135 per year.

This car has many safety features not found on others, it also gives me excellent passenger space with a large boot inside small overall dimensions and drives well.
