Well i got the handbrake sorted with no drama. I took it to Northfield Jaguar specialist. They fitted the supplied, new handbrake motor and MOTd the car, all paid for by the dealer i bought the car from. The Labour was for 4 hours @ £75 p/h for the job and MOT.
I paid for a diff oil change, just preventative, which cost me £70.
When my car reaches 60k i will be having the gearbox service.
Brilliant specialist, fair and they dont rip you off. This will be my go to place now.
