Agreed... Back then when mine was due, called up a few and surprisingly one local insurer dun take in my bolehland car also.I believe you can opt for comprehensive, but have to see type of cars. If it's some ltd edition car, or rare model or hard to find parts I highly doubt so when a door will cost more than the insurance coverage itself.
Insurers have to cover cars because the law dictates it... it's a lose money business, but they still have to make some how. Nobody will insure some hard-to-find-parts car.
