I have been bringing my neon srt4 here for 6 years now and have always been happy with the work they do, I haven't had a DTC in about 4 years. I install a lot of aftermarket stuff like wideband gauges, clutches, blow off valves, etc... and they have never done an install that I had to go back because it wasn't done right. I'm pretty picky about how my car runs and I trust Heno and Alfred. They have done valve cover gasket, timing belt and tensioners, transmission/clutch(shifts perfect and if you know srt4's 3rd gear likes to pop out and I haven't had problems since they did my transmission 6 years ago), etc... They also work efficiently and most of the time they have the car ready within the same day. These guys are good honest mechanics in my book and I appreciate the effort they take to do a good job.
