Im with InsureDirect/Inbroke (same place). They have always been good to me, so I have stuck with them.
Im over 25 and pay $1000 a year in premiums, with an excess of $750 on theft. Ive lost my license twice before and park the car on the street (BG5 GTB) yet they keep dropping my premiums every year and dropped about $500 a year for when I turned 25 as well.
So I would have to recommend them as very reasonable to deal with.
Ohh and they were willing to insure my RS Legacy rallycar for about the same money - this is a car with cage, harnesses, seats, coilovers, different engine/turbo/intercooler/ECU etc.
