8 years ago I was in the same situation.
Speaking to independent specialists the answer was the 4200.
Today you only have to research the engine parts availability, or non availability of certain 3200 engine parts that have put cars off the road.
I came from a similar place, having no experience of either..
Chatting with McGrath's, a well known indy here in the UK, and the two cars were more easily differentiated as ownership propositions...
Not wanting to read too much into the comments but put simply...'we recommend a 4200' was pretty much the conclusion..
LookIng at the pics of all three that rockits posted, I can see the perspectives on the three images varies slightly. That said, the facelift has the edge for me. Cant believe Ive never seen how very pointy the 3200 is. Or how well the slight squaring off of the front end via facelift works.
Does anyone know who penned the aesthetic updates..? Was it Frank Stephenson ?
Ive previously only conceded that the guy has carved a niche as the ultimate 'copycat'..I hadnt understood the scope of his work with Maserati until recently. Whilst clearly very good at the 'reworking' thing- I do believe the 3200 through 4200 to facelift is impressive. Putting the boomerang lights aside, it is a better looking car than the 3200..Can't believe I just said that...(soz Giugiaro, I know not what I say !)
Its okay though...they fooked it up again when they penned the GS updates....!! lol
