Thus by insurance definition, standard vehicle means the one you usually drive everywhere and every time. Also, it includes the meaning that the car is amply available in the current auto-market so that it is easy to replace.
The same specific definition goes with the special cars as well. Here, it means any vehicle which you drive less and or for some special occasion only. Just as the first, and only the opposite, special cars also mean rare types which are not readily available in the market. Thus, if you have any of those classic or antique vehicles, that pretty much belongs to this very category. Needless to say, it is then your job to decide which category your own drive belongs to before you decide to buy its coverage services.
