Yes, you definitely want to sell the 2006 E-350. That one has the bad balance shaft and if yours hasn't gone yet, sell it to a dealer so you don't stiff the next guy with a bad engine. For the 550, get the 2008-2009 models, the 2007 models had bad timing chain idlers on certain engines. Easier to just get 2008+ Plus adding just the E550 engine isn't the same as owning an E550. The E550 had real leather as standard and it also had the cooled/vented seats which were not available on the E350. Real leather was an option on the E350.
