I have an Admiral multi-car policy with four cars and four drivers two of whom are under 21. That costs me over 2k for the year.I swapped the 207 for the 2008 and it cost me an extra £60 for about 6 months which is OK IMHO.I will shop around in April on renewal. Downside is it doesn't cover invoice on write off so I bought the gap insurance which was just over £100 for three years.
Thought I'd better just qualify about Admiral not making the top 40.
