After some advice from another mechanic, telling me that when a timing belt snaps there are no warning signs, i.e. it looks perfect, I got the belt done at BWA Auto.

I paid a shade under $1k for it including all rollers and a water pump. The prices of the parts on the invoice were cheaper than ECS so in all I'm very happy with it.

Armed with that knowledge now I'm going to say follow the interval or if you can afford it go a little before. (here's looking at you Jarred)

Cheers
