Does not matter what you tell them it is worth as they will only pay bottom book price. I got £1200 for mine in 2010. Agreed valuation is the way forward nowadays.
HIC do a good scheme for agreed valuation and is the only way to get back a reasonable sum of money without ball ache

Insurers will look at book value only, Mk3 golfs don't book.
£300 is basically scrap value, hence the valuation.
Not worth saying your car is worth more than this or having full comp unless it is low mile and mint.
If you have a pristine project car, you will not be using run of the mill insurance cover as all your turbo bits and nice paint job will be declared and valued accordingly to ensure you have cover.
I have 20 years driving experience and 10 years ncb, even a 1.0l nudges £400 for me

That's what living near Croydon does for you
