Thanks everyone for your kind words!!
I notified my insurance company (Aviva) by filling form online describing situation.
Those who know the world of car insurance in the UK:
It looks like I'm about to claim against policy of the other guilty driver. His 3rd party policy should cover up to 'millions' of £££ of damage, but it looks like the claim will be capped by market value of the car (or was it 70% of market value). Is that correct?
Here is the hypothetic scenario:
I'm driving a worthless car with market value of £1,000
Someone smashed my car.
Since this is an old car the proper repair cost to original pre-accident condition will cost £20,000
Can I claim £20,000 from guilty car insurance driver?
From what I read here all I can have is £700 (70% of market value) minus excess?
Thank you friends!!
