Hi Peter,
My apologies, I completely forgot to reply to your post.
The majority of the parts haven't been that difficult to come by; the main issue is of course the price as you suggest. Though, I obviously knew they wouldn't be cheap from the beginning. Some parts have been very tricky to buy at a reasonable price, such as a new pair of rubber boots for the steering rack, so I'm waiting on a company that is remanufacturing some.
In short - it's given me more than a few headaches so far.
It doesn't help that Maserati made so few of these cars as a sort of bridge between the 222 series and the Ghibli that followed. As such, technical data and correct workshop manuals are hard to find, and I've been unable to source full wiring schematics for it which could be a problem in the near future. Forget trying to find replacement outer sill panels for a 222 coupe too. I'm having to weld my original panels to the best of my abilities. Thankfully the inner sill is in good condition. All that's left to do really is a bit more welding in the N/S floor, welding on both outer sills, and welding both front inner arches. After that, it's basically a case of refitting all the carpets and interior, refurbing the wheels, and then making sure everything works as intended in preparation for an MOT. When I type it out like that it does seem slightly overwhelming of course!
Regarding your 3200 - firstly, congrats on the purchase. If you need a hand finding parts for it, let me know as I've become all too accustomed to trawling the internet for spares. I find eBay to be an excellent sources of original spare parts, mainly from German businesses such as Modena Parts that advertise on there and don't ask the world for many of their parts (but they do for some items...). I would highly recommend David Askew who is based in Leicestershire, I've dealt with him a few times and the service is excellent. You've also got McGrath Maserati, Scuderia Car Parts, Emblem Sports Cars, Eurospares and Mike Roberts/The Maserati Shed (+ others I'll have forgotten) who can help you out with spares. I would also recommend the SportsMaserati Forum for general chit chat or technical advice.
It's interesting to note the comparisons between the 3200 and the 164. The Maserati will be faster and perhaps more exciting but I think you'll agree the 164 would likely be the better all-rounder.
Kind regards,
Haydn
