 I have waited for almost a year to write a review on my 2014 E350 with sport package in order to live with the car for a while and not make any hasty judgements.  I have always wanted an E 350 and I regret to say that I am very disappointed.  First I would like to say that the car does not exhibit the solidity that MBs are known for. My car has many creaks and rattles from the extensive plastic parts used in the interior.  The standard seats are firm, but extremely uncomfortable; more uncomfortable than any car I have ever owned and I have owned over 20 new cars since I have been driving.  The sport suspension is overly harsh.  All in all very sad for a car costing $61,000.  Beware of MB!Still can't wait for the lease to be over.  I'll never buy or lease another Mercedes product.
