We generally dig Veloce Publishing, they have several great scooter and microcar books. They’re a bit more expensive than we’d like, but March 1 is World Book Day and Veloce is offering 50% off any book.
We’ve reviewed their Lambretta LI, A-Z Scooters and Microcars, and Vespa Buyer’s Guide, and we’re currently reading their Caring for you Scooter, look for a review soon.
