It depends... In the smallframe world the 50ss and 90ss are coveted. For large frame the 8 inch wheel models aren't as popular as the 10 inch models. Any GS seems to be a holy grail of sorts, with Rally 200s getting more and more popular(read expensive). But by shear numbers the p200 has to be the most popular. Parts for most are available, unless you're looking for a early or rare models. Finding quality parts can be a challenge though.
The P125 has sold a hell of a lot more than the P2. The Cosa is a pig to find certain parts for. The SS180 is becoming 'THE' Vespa to own, or so it seems. The TS125 is the one no one seems to know exists.

P200 Day-to-day and Rally bike 'One Careful Owner'
About to start work on building that rarest of beasts, a Cosa chop. It's taken long enough to get this far, the P207 chop will have to wait a bit longer...
Assorted projects I REALLY need to crack on with
Including my wifes T5 Classic, hurry up and paint it!
Id say the P range 125s are probably the most common due to availbility and the licensing laws in this country. Im not sure youll find them all fitted with a P range 125 motor tho'! Other parts of the world you may find more P range 150 Everyone i speak to wants a GS. Im not sure if its a Quadrophenia thing or what really. If the SS 180 is in demand then I think i sold mine just at the right time, when there werent many proper original ones about (and before everyone else gets one) ive seen a few imported ones for sale recently. Its sadly missed but its gone to a good home Id have a TS125 anyday, its basically a Rally200 anyway, which is my favourite. (And my daily ride). Loads more comfortable than an SS180, with readily available parts too. But to me, the wider framed SS looks (and sounds) soooo nice. And its still practical, despite the 5% oil mix you need to run one! Thats a killer! No. 2 on my list is the French Vespa Acma, 51-52. Id love to 'tastfully modernish' one of those. Parts are bit of a nightmare tho'. 3. SS180 Anything with 10" wheels and a rounded toolbox behind the legshields would do me well Ive not seen many TX200 GS either. Thankfully
