Might be getting a new car if the finance approves this week, i will be getting a more cost effective car

the renault megane.
Its a 1.5litre turbo diesel brand new although its been pre registerd with the 55 plate its got just 24 miles on the clock.
It costs now just £667 a year to insure and £50 to tax and diesel is alot more fuel efficent and cost effective.
Now compair that to my old car!
My old car is a rover 827si a V6 engine with 2.7 liter sports injection (2,724cc) cost to tax was last year £175 as of this year £225 insurance stood me at over £2,150 per year on my fathers insurance, on my own 3rd party fire and theft £5,549 per year.
