Modern Vespa

I'm looking at buying a 1961 VNA (with the 2-piece split headset), the bike is all original and in nicely restored condition (but not quite immaculate show-worthy state), mechanically it is pristine/immaculate, with its original engine (completely rebuilt by a trusted local Vespa mechanic) the piston on this bike has been bored out to 150cc, it retains the original size 8" wheels.

This is a bike that I am quite familiar with, as the restorer/owner is a friend I ride with semi-regularly (who has helped me quite a bit with problems with my current not-so-lovingly-restored ride/moneypit), and I am also very familiar with the the skill of the mechanic who rebuilt the engine. In short, this scoot is a known commodity, without any uncertainty of condition in my mind.

I see prices all over the place online (and many of these bikes I see for sale appear to be asian-bodged messes). What does this forum think is a reasonable price to pay for a scoot such as this? ...what is the upper end of reasonable? Thanks in advance for your thoughts/opinions.

Without pics, i really couldn't tell you.

To me, even in decent shape... not much.

There's so much to do to a VNA to make it move fast enough to run in traffic...

not much. sloooooooooooow.
