Being that I have had a total loss with Hagerty, I may be able to help here.
In 2016 my Spyder was insured for 35k. I had a collision in March of 2016 that was a total loss. After the buyback, I think I received 31.5k or so. They only took 10% for the buyback fee. I stripped the old car CLEAN, cut up and disposed of the body and frame. I bought a new body and frame that was painted by Greg's guys. I sent him some parts, trailing arms, spindles, column, steering box.
When it was finished and shipped 6 months later, I started assembly. Motor, trans, brakes, etc. I ordered new gauges along with a cable shifter. I had the car done 6 months later in time for Carlisle 2017. A bit over a year and back in business I was.
I was decidedly in the black in the bank, IF you don't count my labor. I really enjoyed building the car again, so I didn't count the labor. I knew exactly what NOT to do, and I was able to fix/change a lot of things that I didn't like about the first car.
I retained my insurance the entire time, and have bumped the coverage up over the years. I think I'm at 45k now, which is probably still too low.
Hagerty was an absolute pleasure to deal with. The totaled car was in my garage and the adjuster came right to my house. He saw the tweaked tubular frame and that EVERY panel on the car was cracked except one: the passenger door.
I wonder if the ban is Speedsters only or if it is ALL replicas? I also have my Cayman with them, several years ago they added any year Porsche, not just classics or antiques.
I'm sorry to hear about this, I'll make sure I keep mine "grandfathered".
