I have had Leland West for about 4 years now and one of my friends has a 69' Nova with a 598 BBC with nitrous and he has had them about 6 years now.
I looked around at the big names for classic insurance but since my car is highly modified along with having nitrous installed made it tougher to find someone
that would actually insure me.
So I ended up going with Leland West, I have an agreed value of $35,000 which has stayed the same since the beginning and also I have the buyback option since
most of my money is in the drivetrain I wanted this included in my policy.
I did not get an appraisal but I did have to send them a crapload of pictures including my car in my garage and my classic license plate and odometer.
I sent them copies of receipts for major parts and had to do an extremely detailed breakdown on the work and parts installed.
Also I sent them details about the garage like no windows, steel man door with commercial grade deadbolt along with hardwired and wireless alarm systems.
I think any detail you can give them that makes them feel your car is secure in your garage helps, I probably even told them I live on a dead end street and we have a
neighborhood watch.
I pay under $500 for the year but I also have an absolutely flawless driving record.
