Hello G- fellow fighter, am superior my G55 for a G63 old to exchange. I am actually very happy with my 55s. Sound is the hammer, kicking bombastic. Who has experiences or acceleration, chassis harder or softer, transmission, consumption etc. Interior equipment is clear anyway. Weis already, the eternal debate with the consumption, measured with my average 19.8 l and that at 40,000 country road kilometers. With mobile because of price determination look. Not really many in the Net, if you pull off the under 500 hp. No 50 STÜCK !!! more, in contrast to the 63s, several hundred. Makes me think a little bit. With friendly G—sweeten Manfred
