Insurance issue


Hi, im new to the forum and currently own a 2001 Daihatsu Atrai 7. My insurance is up for renewal but trying to obtain quotes is a nightmare as majority of company's dont have Atrai on their systems (even tried a few jap import specialist), but however a few have quoted me based on my vehicele being a Hijet. I wanted advice on this as not 100% sure if insuring my vehicle as a Hijet would be legal.

Any advice would be appreciated
