I’m with HIC, and I got an agreed value on my MK6 escort, as said it’s an extra £15 to pay but worth it
I quoted an amount I thought it was worth
they sent out a 4 page form
Then I filled it all out and sent it back with pictures of my car, the engine bay and copies of receipts to back up all the work done and sent it back
They then send this info to someone to check to see if it is worth it and they just sent me an agreed valuation certificate to the value I quoted
Also tell them if you go to shows, and what ones you go to and that you are a member of car clubs
