There's a guy at Maserati UK who has all sorts of usual information, way more than a MD in my opinion. He is Paul ... something. His name escapes me right now but I have his details somewhere here.
If you're still struggling Dave, I'll try to dig it out for you
There is also a list out there somewhere with production figures for each year, so combining the two you should be able to get a good idea. I'll see if I can track it down.
Nice one Stu,Its just out of interest really..
As some of these old cars when new were sitting around in dealer's showrooms for 6 or 9 months before they were sold and registered for the first time..
