OK lads I've just taken out insurance with Brentacre (awesome service from Gary

) but my car is insured for £3800. However, when new mine was £24500 which was more than the Racing Puma, which was out at the same time. However, the Puma is selling more at £5500 to £6000 for decent, low milers. My car has 76000 on it now on a 2000/W plate.
Should I be valuing it nearer the Puma prices or around where it is? I can post pics and spec if needed.
Am only asking as I was considering Agreed Value on my policy.
