Spud - i had to order new locks as some tube lost the actual door key so the car couldn't be locked. Helpful . . .
The new locks come with cables and will be here tomorrow so all is well laugh

As for oils, i got the 75-140 from BMW and then got some Mobil 0w-40 fully synth (recommended by BMW) for the engine.
Boy the woman wasn't happy with me! haha. Asked for the recomended oil for the 4.4 V8 engine thats in the 645 BMW. Whats the reg of the car in response. Its not a BMW, my car just has the engine, then she had a rant about it. told her to stick it and that i would just find the engine oil cheaper else where. Silly bint! :p
