I agree that the Murtaya does look out of proportion from front to rear from some angles but considering the physical contraints of the boxer engine forward of the front axle line I think the "front-heavy" look has been minimised quite effectively.
I quite like the look of the MNR Vortex RT+ as a seven style car. For something different you could get a GKD Evolution, they look cool and currently being developed to take BMW engines and components.
