The top of the line older models are about as fast as ISF with semi-manual box and extra hp. ZF6 is usually a preferred tranny but limits the performance....no match for ZF8 or ISF 8-speed.
But the looks, the sounds, and that engine....damn....08 low miles 4.2l sold for $33k locally. Quattroporte go even cheaper now days.

 

MC Stradale go for less than half of their MSRP these days. Badass luxury cruiser with some pep, but they aren't focused on performance thus wouldn't buy one with those intentions. It's a weekend cruiser date night car. Fit and finish with an amazing exhaust note and something a little different.

Unfortunately we dont even get the true Stradale in the US.
