if you are ever up north (stoke on trent) then let me know, I had the following done in Jan 2018 on my LS 430, I spent £311.38 on:
INA timing belt kit
8 bosch spark plugs
oil filter
cabin filter
denso wilper blades (OE)
Brembo front pads
Brembo rear pads
air filter
2 x 5lires of shell helix
All the above were from euro car parts, in Jan my A/C wasnt working due to a leaking condensor so I sourced a used one for £30 and got my mechanic to do the full service with all the above parts, brake pads front and rear, he replaced the condensor, timing belt kit with all pulleys etc and done an mot on it for.......wait for it
£180 labour and this included the MOT.
I have since done 4k miles in the car and hasnt missed a beat.
So I spent just short of £500 and had a lot more done to the car. Coolant changed to ofcourse as it is with cambelt and waterpump.
