As title. Just had my MOT. about £310.
Had to get the handbrake fixed (replaced cables, bolted the lever down), replaced rear break cylinder (was leaking), front cv joint protective boot, front ball joint and finally the hazard light switch.
Thats on a Peugeot 106, at an independent garage. While it was a lot of stuff to be fixed it probably is quite a reasonable price.
How much did your last MOT cost you? Vote and post your car and any problems you had and how you got them fixed.
