Hi all, Anyone had experience insuring someone under 25 on a MV. Looking at getting myself a 1980 Pinzgauer 710 but seems like getting insurance as a 20 year old having had a driving license for 3 years seems to be impossible as most brokers seem to have a minimum age of 30 or 25. Anybody got any tips or will I have to wait a few years? Regards
