Electric start? Two seater? Before you get serious about buying, Google “Viet Bodge Vespa”
If they are not “viet bodge” they would be worth between $1500 and $3000 each. Of course, that just depends on condition. But I suspect you are going to be sadly disappointed after you Google.
Here is my 1980 Vespa 100 Sport. It is not a Viet Bodge.
