I've used Lant for years. I have never made a claim, so I can't tell you anything about the claims service, but I can tell you they are very quick to cash my cheques

. I currently have a 78 Mini, 73 MGB-GT and 71 E-Type Jag insured with them.
I haven't put my 1990 ZR-1 on the road yet, but I coincidentally just had it appraised on Wed. and called Lant yesterday to put the insurance on it. I had mine appraised on the low end of the scale given the current market, but still for more than I have into it. The chances of anything happening to the car are pretty low, and the higher they apraise it, the more you pay, and the insurance companies like that!
I picked up some brochures from a couple of other companies that are now offering collector car insurance when I was at the RM Car Auction in Toronto a few weeks ago. When my insurance policy comes due in the fall, I'll likely call around and see if Lant is staying competitive.
