Mate got a Groupon voucher for service and MOT on his 2002 Fiesta.
MOT failed on Rear offside amber indicator not sufficiently amber. Cut rear tyre showing to ply. Front to rear brake pipe nearside excessive corrosion. Front to rear brake pipe offside excessive corrosion. Rear brake pipe nearside excessive corrosion. Rear brake pipe offside excessive corrosion. Nearside rear suspension bush excessive movement. Offside rear suspension bush excessive movement.
Quoted, bulb ~£3, tyre ~£40 (had it done), brake pipes £180, bushes £180. Said they had to drill the bushes out and it was a nasty job.
OK so I could do the bake pipe for the cost of a length of copper tube maybe 1hr. Had a look at bushes ~£25. Manual says take rear suspension off. Piston heads says put car on rear stands, remove wheels, drop exhaust on to suspension, support torsion beam, undo bush bolts, lower beam on to blocks. Use a bush extractor ~£35 off E-bay or £120 for "pro" tool. I'd go for bit of heat from a blow torch before.
Then without doing any of the work except the tyre he took it to Halfords and it passed. Was advised to grease his brake pipes.
