u r talking about a single entity vehicles
it is very common to represent a single entity with a single table
and IF u also have to have an entity "class of vehicles"
u r free to declare the second table named "class"
and IF u also have to represent a reference of manfacturers, another one
table u have to create then.
that's trivial case
