Ive had no issues with AEM X-series guages although only had their uego on my old 240sx. Plan to go with their uego, oil temp and boost on another car.
Back in the day recall people willing to spend more go with Defi guages. They did look good, have a reputation for being more accurate and reliable. Never did use them myself. OAKOS might sell them

Pretty satisfied with the accessport on my Fiesta and yes I always remove that or any other electronics when I park my car. Think also it'd be hard to have 3 guages in the fiesta look good, unless you are okay with the 3 guage pod in the driver's side A pillar.
