Ive been going to Phase Four for years... Ive had everything from headliners put into cars (tricky ones too with moonroofs, dvd players, and consoles on the roof), remote starts, alarms, moon/sun roofs, and keyless entries installed on various vehicles. Their prices are very reasonable and Ive never had a problem, thinking back on it. I just called them a few minutes ago to have remote start installed on my Envoy, and they again were the lowest price and can get it done tomorrow before noon, if I drop it off at 8am.
Pros: Fast, reasonably priced
