HAHA!
I'm in a similar boat to you, and just did my car insurance last week (for the 3rd year), and got the price down to £480, (£550, but £70 cashback in 3 months time). Fully Comp, with MoreThan.
Never paid more than £700 for fully comp. since day one, (that seems a long time ago now!
)
I know those insurance sites like the back of my hand, so drop me a line to see if I can help save you a £1000 or so
(I'm not promising!)
As for a 'bangin' sound system, scratch that; and stick a 1W moving head green laser bolted on the roof rack (you can use the money you saved on your car insurance to buy it
)
