IS THERE A DIFFERENCE BETWEEN 2014 MERCEDES E-350 SOLD IN APRIL OF 2013 anD 2014 MERCEDEDS SOLD IN 2014

From Wikipedia....."In 2013 (for the 2014 model year), the E- Class was comprehensively facelifted. Daimler invested close to €1 billion into the development of the extensive refresh,[9] making it likely the most expensive mid-life facelift in the history of the automobile.[10] The front fascia was heavily restyled, giving it a more aggressive look compared to the pre-facelift model. The biggest change was the singular front lights replacing the twin headlamp design (marking the end of Mercedes's dual headlamps use) with LED DRLs. The facelift was meant to make it more appealing to younger customers, who prefer its newer rivals (Audi A6 (4G) and BMW 5 Series) for their more modern looks.[11] Most of the engines remained unchanged from the previous model. The Coupé and Cabrio shared a more aggressive, swifter look than the sedan, with a more svelte front fascia and a sleeker bonnet. Although not an all-new model, majority of the auto world have stated that the updated design and several changes make the car more than a regular mid- cycle refresh.[12] On a family portrait of several generations of the E-Class side by side by Mercedes-Benz for the unveiling of the W213 E-Class, the W212 facelift was the only mid-cycle refresh featured in the image."...https://en.wikipedia.org/wiki/Mercedes-Benz_E-Class
