Hagerty Insurance issue

I just attempted to get a quote from Hagerty for a 2000 Subaru Sambar. The representative proceeded to tell me that it is not in their system and that it has to be OVER 25 years old in order to be insured. So a 1999 model year Sambar (no matter what month it was manufactured) would have to wait until after the new year to be eligible. This doesn't sound right to me at all.
