Ive had a really good bloke service my cars over the yrs and I trust him, I even bought my current car (Alfa 156) off his son, the thing is I checked with him to see if he was ok with servicing the Rotary ... and he said he wouldnt touch one and neither would anybody he knows which has kinda thrown me to be honest.
I think alot of people more so mechainics are wary of Rotary engines as its so far removed from everyother car that comes through their doors, I think maybe as well horror stories of over tuned, raced/raged poorly maintained 7\'s probally dont help.
Out of interest do you use main dealer, specialist or independant garage?
