I hope you don't mean the AA when you refer to your local expert.
My CT26 went at 170k (standard boost - 8 psi), Clutch at 198k, Head gasket (rebuilt it) at 215k then the cambelt tensioner let go causing the belt to snap at 220k. But great cars really

Just a pain in the arse to work on and very demoralising with all this happening over the course of two years.
