Hagerty is an insurance company they insure your car on an agreed value. That being said I’m ¾ done with my Mark II, it’s not on the road yet I have increased the insured value to $90,000. They have agreed to cover my loss at $90,000 if the car is destroyed. The values that they have place on their web site are values that they will pay. When I get this car done I’ll most likely insure it with them for more than $150,000.00 based on my cost records. If it were to sell at auction for over $200 they would insure it for that. Knowing this, I Think that Hagerty has a better handle on values than most other sources. I get several value guides each month and one of them is OLD CARS REPORT they have a 1960 Super 90 Porsche Roadster #1 listed value at $66,000. The last one that I know of that was bought cost $150,000 and it is a # 4. This book is not very accurate with foreign cars and yet they have the Mark II at $90,000 for a #1.
