No disrespect Kleyklamp, but IMO verbal assurances from an agent are not worth the paper they are written on. The written policy is the legally binding agreement, not whatever your agent told you.
Don't get me wrong, I like my Mercury agent (and the people who work for him, I've not seen the actual agent in many years). They try hard to be helpful and explain to the best of their ability, find ways to lower my premium, notify me when there is a problem, etc. But they are only selling agents, not the company issuing the actual insurance, and not involved in the claims process at all. And they don't always know everything, especially when it comes to something that is new to them.
They actually didn't even know that Mercury would agree to insure my TR3A initially, they don't normally write insurance on cars too old to be in the actuarial tables and so on. I don't know, Mercury may have not agreed if they didn't already have my other insurance (and offer me a discount if they insured all my cars and home). But they did.
It was a bit disappointing that they could not help with getting the TR3 repaired this last time around. They have a list of shops in the area that they contract with, and a proviso that they will 100% cover any subsequent repairs caused by a poor or inadequate initial repair, if the work was done by one of their contracted companies. But none of their shops were willing to take this job.
But honestly, I prefer that to being coerced into using a shop that just wants to slap a wad of bondo on. So I'm not too upset at being left to find my own shop (or as happened, do the repair myself at premium rates).
