Oh c'mon, what's that all about?
Seriously though, The Ford Taurus SHO is an incredible machine. It's a little pricey but compared to its competition and comparing HP and performance, it's quite an unusual mix of practicality, low range luxury, and power.
Listen, the Taurus SHO doesn't really compete with the Q50 on any level other than price point. The Taurus is a large car and not tuned for sporty or spirited/aggressive driving per se, but it's probably more fun to drive than the majority of the sedans in the large family sedan segment.
Are you sure it was $48k? I know it starts at around $39k now but there Taurus still has a lot going for it (I know---I've done extensive research on the car back in 2010).
Also, whether it's a Ford or not is pretty irrelevant in the grand scheme of things. The Ford SHO is shocked filled with features and is, to me, the Q50 of its segment from a technology perspective (having several features that the Q50 currently does not have)
