1995 BMW 540i (original DOHC v8 car so swap would be easier) with either a coyote or 5.3 LSX. Either would have at least 1 turbo.
Totally agree Gravik, it would be an awesome sleeper with style! Would love to do this some day.
Personally I would love to do an Unrestored, patina'd 50's ford/mercury 4 door sedan, bagged, z'd frame, mobsteels, coyote swap, and maybe a turbo.
