When it comes to ABC, you either have to have a good warranty in place, have deep pockets and not care for the cost or become handy with a spanner. I've tried all 3 options and found the latter to be the best one for me. It cured my fear and frustration of driving and expecting something to go wrong, it saved a hell lot of money and time as flat rate mechanic's approach is usually to replace everything until it starts working again.
In case I ever upgrade from airmatic to ABC, could you say what ABC system maintenance is possible using a spanner?
My car had failing front airmatic struts when I bought it too...previous owners avoided replacing them due to cost, I'm sure.
