""I see your point, however the insurers will still be covering the value that you give them, which would no doubt be the"" ""price of the vehicle and the optional extras!""
Negatory!
The insurance company insure the car you tell them!
The cost price of the vehicle is used only as a guide upon which they can base the cost of any possible repairs.
They look at the ability of the car (and the likelyhood of the driver) to top gun round our roads like a drugged up pillock, how many cars were knicked in your street last year, how many of your chosen steed have mutilated there ocupants in a collision, factor in the repair cost multiplier, assess the total implied risk to them etc etc. This then gives them a figure upon which they base the premium.
Unless you have a classic (or otherwise precious) vehicle on an AGREED VALUE policy, (which means inspected and valued by the company, its representative or and acredited body) they will only usually pay out "market value" in the event of total loss.
On a brand new 12k vehicle thats about 9 or 10k from the minute you drive it off the lot.
If you are in any doubt, look up gap insurance. It basically covers the difference between what you owe on the vehicle and what the insurance company are prepared to pay out. It may be something you need to consider if getting your car on the never never.
If you want really irritating, I was the victim of a hit and run at 2355hrs on the night that I changed insurance companies.
That means means that I was insured by one company at the time of the collision and a different one by the time I managed to get out and contact the police. AND I was only TPF&T so I couldn't claim off either of them. Try declaring that one...... TWICE HAHA!
