I got a quote from Grundy and it was interesting to note the drivetrain + engine must remain stock and unmodified. So I guess you wouldn't be able to do jdm short gears or swapping out the differential? Or would that not really matter?
The restrictions are not bad for the average enthusiast, but for one who takes the NSX on errands, would it be better to stick to Geico? I feel like any choice that makes me want to drive the car less is a bad one.
I have American National now for ~$45/mo for great coverage, but they require professional appraisal for agreed values over $40k so I'm looking to switch to Grundy as well. Just turned 25 so they'd finally agree to cover me.
Grundy seems to have a good collector's policy, unlimited miles as long as it's not your daily. I would have no problems taking the NSX out for occasional errands in that case, it seems to fall under their terms of coverage just fine. I have a modified transmission but have not seen anything on their terms about forcing you to remain stock, in fact they seem to lean fairly liberal with that:
From their website:
"What Types Of Cars Do You Cover?Grundy insures most types of vehicles 25 years old and older. We also insure modern muscle cars and exotics of all years. Not only that, we insure modified vehicles with higher performance engines, suspensions, and modified bodies. We understand custom vehicle valuations very well, and in fact Grundy is the largest insurer of hot rods in the USA!"
"Grundy wants you to enjoy your car, not keep track of mileage like some programs with limitations. Therefore, we give you unlimited miles for pleasure driving and in collector car-oriented activities. It is even OK if occasionally you drive your collector car to work to show it off to friends. However, your collector car must not be used as a daily driver. We require you and all licensed drivers in your household to have a modern car for everyday use.
When you have your car at home, it must be kept in an enclosed, secure garage when not in use. If you are away from home on extended outings your car is fully protected if you must park it outside, for example in a hotel parking lot. Grundy coverage includes Trip Interruption that reimburses you for hotel and repair costs in the event of a breakdown, and we also reimburse you for towing and labor charges up to $250. You can count on Grundy as you cruise."
They quoted a bit higher than AmNational but don't seem to require professional appraisal which is a huge bonus to me. Hagerty is great and all, but they quoted me like $350/mo for average coverage which was absurd. 700% more than Grundy or AmNational.
