I went to John's Foreign Cars several times since I bought my car last year.
The "green" coolant flush (required every 3 years for my car) was done at Hatch&Sons.

I also went to Chambers, Sommerville. An unsatisfactory job done there was roof trim (water shield? from A pillar to end of the roof). The end part was loose and the rubber did not match. They just installed new clip to make it tight, but did not adjust the rubber position. The service advisor pulled the rubber to the end at my complaint, but now the rubber recessed back leaving a whole at rear - water will go in and make rust -. I should have requested complete reinstallation.

The tranny leak done at Chambers seems to be OK. I do not see fluid below my car anymore.

If I do the flush myself, how do I despose the fluid?
