Excellent post, full of very good info for the 355!
I would only care to add to the above point, regarding the "sticky throttle" issue which has aggravated many a 355 owner...including myself!
It was usually associated with earlier model year cars, especially 1995s, although it could effect any.
In my experience, this was not only a lubrication issue, but a design flaw in the 355 engine. You see, the throttle cable is enclosed within a jacket tubing which runs through some of the hottest parts of the 355s engine. The cable itself is made of a plastic material, and over many hours of exposure to this engine heat, it begins to fray, kink and melt! This leads to it getting caught up/stuck within the cable jacketing, which in turn leads to the occasional sticking. The best solution is to replace the melted/kinked throttle cable (you'll see what I mean when you see it...) and insulate the cable housing with some heat resistant material, so as to slow down the process from happening again. This and some lubrication can usually cure the problem by upwards of 90%.
It makes a day and night difference in the driveability of the car....when I had the problem, it made the car virtually impossible to drive smoothly when going slow, and could be downright dangerous sometimes (especially after re-applying throttle after a turn...)
