You didn’t mention what you might be looking for as far as type or how much you’d be interested in spending
You might look at the york/baltimore/harrisburg craigslist and possibly put a want ad there, I did that last year before I got mine and found a local Stewartstown guy who was interested in selling but hadn’t done anything about it, so it was really a private sale and I got a good deal.
For anyone else possibly interested in just a daily small commute rider, this seems interesting

A 30 year old moped that probably gets near 100 mpg for $475........you won’t find one of those new scooters for that price, and it’s a JC Penney
