Just curious: does anyone here know of an independent new scooter retailer who has been in business for more than 5 years, does not sell the Vespa brand, and has no other means of support? I don't. I've seen a lot of them come and go, but I'm not aware of any thriving scooter shop offering second tier brands who can make a profitable income solely from sales and service of new scooters. Loving scooters and thinking it would be a fun business and "hope" is not enough. You need a solid and realistic business plan, and most likely once the hard work of developing a business plan is done, that's all the info you'll need.
The last one I knew of just announced they are closing their doors, and they enjoyed a great reputation and a large metropolitan market (Los Angeles.)
