I can add a third voice - except I did do some preventative maintenance first (suspension arms, steering rack, clutch, cambelt, thermostat, water pump. Plus a fix for the existing fault (replacement steering column). And a replacement for the Connect Nav+.
Since getting my Stilo back up to standard, it has performed reliably for over 10,000km with no new problems and I get the feeling it's a good one.
The thing is, the three of us have good Stilos... but unfortunately, there are a number of bad Stilos out there. Those Stilos never worked properly from day 1. I've worked on three of them and it seems to be one crisis after another, with always a final new niggle at the end of any major job. E.g. the engine wasn't running, now it is, but there's 'Brke Lamp Fail' on the instrument panel.
So I guess the moral is - get a good Stilo, and it will be good to you...
