Insurance is a funny thing, not in the "Ha ha" way though.
Tbh I think that sounds a little rich.
I was paying £495 fully comp with Adrian Flux and that was for a heavily modified supercharged '03 Zed with 436Bhp. I'm 35 with around 11 years NCB, car parked on driveway over night (standard Nissan Cat 1 alarm/immob etc).
The thing is though it will obviously make a big difference the area you live in, crime statistics etc for the area. I'd say just go on a comparison site to see what better prices you can get.
If you haven't used one before it's really easy (takes maybe 20 mins). Just be honest, add all your details/car specs, NCB's etc and they'll then generate your quotes from hundreds of insurance companies based on the info you've provided at the end with the lowest priced ones first.
