The MG 7 is a sports saloon built by Nanjing Automobile, derived from the Rover 75 and MG ZT. Production started in early 2007. The MG 7 has received praise from British car magazine Auto Express, who test drove it in May 2008. The MG 7 comes in two variants, the first which resembles the Mark I MG ZT with twin front lights and the second which resembles the Mark II Rover 75 V8. A long wheelbase version, called the MG 7L, features the deeper radiator grille of the Rover 75 V8. The MG 7 comes in two trim levels: 'Classic' which features a slatted grille, and 'Sport' with a mesh grille. The look of the 7 has changed very little from the ZT and 75[citation needed]; the only noticeable difference is freshly-designed LED rear light clusters and new alloy wheels. Also the car features new audio and heating systems as well as a new sunroof system. There are two engine options, the 1.8T and the 2.5 V6, both revised Rover K-Series engines called the N-Series with stronger head gaskets, both meeting strict Euro IV emissions regulations.
