First one looks more like 4.2s were spec'd (silver headlights, quad exhausts etc), but as others have noted, trying to be overly specific on models/specs is hard
Second is an auto. Facelift cutover was late 2012, but they didn't cutover as you could still get the old face into 2013 at least (I think there's still an old look 4.2 out there for sale that's a late car - may even be 2015/16!!). The interior's interesting....it could be one of those that Italian cars get away with.
I think someone posted the third (Quirks) car before? There were quite a few facelift cars in that colour (think it may have been the brochure colour).
The last car confirms what was noted above about release dates and is too expensive IMO
The facelift cars
did get more power. 460PS versus 440PS (and I think the 4.2 was 400PS). A PS is a bit more than a BHP
In a car that weighs 1800kg you can't really tell its there...but it's nice to have it and won't hurt.
