I've just been using Landmark Ford in Tigard, but then I haven't had any real issues in the 85K miles I've put on the car.
I had Aldridge Motorsports do all the mountune installs because the were a Ford factory approved racing shop and the mp 215 had to be installed by a genuine Ford shop to keep the warranty...... They've since moved out of Portland and are out in the boonies in Clark County Wa now, .. but last time I visited they weren't doing Fiestas anymore. In fact mine may have been the only one they ever worked on..... .. Now this was nearly a decade ago so again I've just been using Landmark. (I bought the car at Courtesy Ford, and they did the servicing for the first few years, but then they went to some sort of Quick-Lube thing so I haven't gone back since)
When my slave cylinder went out, (and my blend door) I went to a small local place in Longview that took care of that and the clutch replacement (brakes too). They're pretty good but don't have access to some factory info. For example, to program key, the mp215 tune must be removed. If the shop doesn't have the ability to hook up to the genuine Ford Factory computers it can't be removed. I had this happen when I wanted a replacement key. The local FORD dealer themselves couldn't figure out how and claimed that the connection with the factory was down (for a week?) and I had to go to Courtesy Ford where they unloaded the tune, programmed the key and reinstalled the tune. .... A very expensive extra key!
