I've been with JustCar for the last few years, they've been great with modifications and agreed value. Unfortunately they're closing down this year.
I inquired with Shannons and it seems they won't insure if the vehicle isn't garage parked at night - is this the case with you guys too?
Most other insurers seem cagey with agreed values and don't take into account the condition of the car and whether it's actually worth more than the "red book" value (which seems suspiciously low) - the best number I could get was $6000 (with a hefty premium) - most won't go above $5k!
