I will just try again. Firstly, thank you guys for letting me have your thoughts and advice and I can assure you that it is not a wind up. I live in Jersey which is relatively flat and only 45 miles square. The top legal speed anywhere in the Island so I can assure you that the car has not been ragged and I certainly do not rally drive. I use the car for work every day but as you can tell by the mileage for a car that is getting on for 7 years now, that is not a lot. I do know the garage and largely trust them and to be fair they kept the car on the ramp so that I could see for myself that the bushes are knackered. I did take the car to the main dealer last year to have a failed front bulb changed and they quoted me nearly £600. The cost of the part was excessive and they said that to get to the bulb they had to remove the front bumper with the sensors and other bits just to get to it. That is when I went to this other garage and he ordered the part from the main dealer, removed the front wheel and got in through the wheel arch. Total cost with the part £140. So, you can see that I think that they are genuine and in fact his quote for labour on this one is £160 which is 4 hours work, all the cost being for the parts, although I guess that he will have a percentage in there.
From what you have said it looks as if I will have to bite the bullet on this one as if the cheaper parts did not last for 2 or 3 years then I would take it as a false economy.
So, unless someone comes up with a credible option I think that I am stuck.
I would like to thank you again though guys for taking the trouble to reply, I appreciate it greatly and can see myself making good use of this owners club forum. Cheers.
