I'm with TD Waterhouse insurance, and when I was under 21 they wanted photos of my vehicles. I would send them photos right after I purchased the vehicle and would then modify it, but since I just had liability on them, if anything happened, it's not like they were going to cover me for any repairs or damages. They haven't seen my past few vehicles, but I'm pretty sure that if they saw my old B2200, they wouldn't even recognize it compared to the original photos I sent them.
They no longer require photos, so the last couple vehicles I've owned all they asked me for the the VIN, year, make, model, colour, number of doors, engine size and 2 or 4 wheel drive. They then calculate my rate based on where I live, how far I drive to work, how many miles I drive per year (more miles means more risk because you're on the road more often), where my vehicle is parked at home, if it has any anti theft systems, and then take into consideration the year of th evehicle, my age and my driving record.
