Interesting thread - surprisingly timely.
We're about to swap the CLS (sob sob) for an E Estate. I consider the A6, C Class, BMW 5 Series Estate as well.
Drove all of them.
E Class - surprisingly agile, didn't feel huge, but it's enormous inside and an incredible ride (should add it had airmatic - which makes a difference).
A6 - nice car, but didn't feel the value. price seemed to be out of proportion with the car.
C Class - lovely car - really nice. However would only want one in 63 form as it's a total hoot in that regard. Otherwise with the options we're going for the E makes more sense fiscally.
5 series - expensive ! Really expensive - if you do like for like with an E and look to have a reasonable number of options - E wins. In my spec the 5 series came out nearly 7k more. Plus I think it's very ugly.
E wins - new one to be ordered shortly, for 12 plate....
which E estate? Spec?
why not wait for the CLS shooting brake ?
