As above, first thing is to check that the engine's not seized. If that's OK then there's almost certainly a fair bit of work to do, though it might not be that expensive...IMHO.
- drain fuel and add new - probably wouldn't run with 9 year old petrol...
- oils and filter change (cheap and easy if you are handy and have ramps - you haven't said if you are able to DIY this?)
- new tyres (probably biggest cost! + spare..)
- free up the brakes (very possibly seized, probably discs are rusted to hell and need replacing, which means pads too. Probably not too much ££ if you can DIY). Brake fluid would need changing anyway.
- gearbox oil change
- battery
- coolant change
- wipers
- air filter(s) (could be OK)
- plugs (could be OK)
- belts/chains..
Maybe £300 for parts (excluding cambelt/chain) + another £250 for tyres...then £50 for MOT, £170 tax + insurance.
