Car repair cost questions

Hi guys,

I haven't had much luck with cars over the last few years! This morning my Corsa passed its MOT but with the following advisories:

- Sub-frame corroded but not seriously weakened front

- Exhaust System Deteriorated

- Tyre Worn close to nearside rear

- Tyre Worn close to offside rear

- Shock absorber has a light misting of oil nearside

- Shock absorber has slight corrosion to the casing rear (both sides)

- Suspension arm rubber bush deteriorated but not resulting in excessive movement front (both sides)

- Coil spring corroded nearside front

I bought the car 12 months ago for £3,000:

Brand: Vauxhall

Model: Corsa

Year: 2007

Engine: 1.4L

Does anyone know how much these repairs will be? At the moment all I know is that I can get part-worn tyres for £20 each

If the repairs are going to be really expensive I am thinking of selling the car

Thanks for your help,

Anthony
