Hi all,

I am thinking of upgrading my W124 to a W210. There are many low mileage E320 with the straight 6 (M104?) out there that are reasonably priced.

Can anyone comment which is the better buy?

I've read about the seals coming off the balance shaft pulley in the V6 engines. As the in-line 6 has been around for so long, is this the way to go?

Thanks!
