Morning,
Firstly many thanks for all your help and support so far, it's been hugely beneficial to me.
I've now had the vehicle inspected by
http://www.millenniumcroydon.co.uk/ and they have advised the following regarding the suspension:-
Front lower arms very worn (I saw that the bushes were almost none existent) causing knocking under braking and on uneven surfaces - Supply and fit = £690 + VAT
Front and Rear shock absorbers efficiency very low causing instability of uneven surfaces - Supply and fit = £1230 plus VAT
Verbally they suggested that at 70k miles they presumed the vehicle had been used as a tow vehicle throughout it's life.
Separately from the suspension, the rear nearside caliper is somewhat seized and the wheel will not turn freely whilst up on the ramp - They quoted to supply and fit (pair) £617 + VAT.
I don't know how those prices compare to what you guys would expect?
Next step is to contact the car dealer I bought it from a few weeks ago and see how I get on. Frustrating times.
