And a few more limited edition Porsches from their long history of limited editions:
1973 911 RS - approx 1,600 produced, unclear on the number of US versions, performance package, race homologation
1974 911 RS - haven't found production numbers, performance package, race homologation
1980 911 Weisach Edition to recognize Porsche Motorsport Team in Weisach- 400 US cars, trim package
1982 928 Weisiach - 204 US cars, trim package
1982 924 Weisach - haven't found production numbers, trim package
1988 944 Celebration Edition - 500 US models, trim package, in recognition of 100,00 cars off of the Neckarsulm line.
1992 911 RS - 45 US models, performance package
2008 Boxster LE - trim, aero mods, minor engine mods, 250 S models, 250 base models
2014 911 50th Anniversary - trim and performance, 1,963 produced, unclear on US versions
2015 911 PCA Edition - 60 models, trim package
As for value, in the above examples from the '92 RS and earlier, none of the trim editions appear to add much or any value, the RSs bring premiums even the '92. Keep digging though, there are more limited edition Porsches out there.
As for 914 LE, the market is what it is, logic doesn't always prevail, but it doesn't on Wall Street either. If the surf is up, ride it... The question is, is the surf really up? Time will tell.
The Porsche 911 GT1 is a car that was developed in 1996 for the GT1 class in the 24 Hours of Le Mans. In order to qualify for GT racing, 25 road-going models were built to achieve type homologation. These models developed around 700 hp (522 kW; 710 PS) and did 0–60 mph in 3.3 seconds. The top speed was 235 mph (378 km/h). Both the road and race cars carried the same twin turbocharged engine as used in the 962, and the race car was a match for the McLaren F1 GTRs that were racing at the time. A re-developed version of the 911 GT1 race car was later built, winning outright at the 1998 24 Hours of Le Mans. The car is not really considered to be a real 911[citation needed], as it is derived from the 962 with the 996 911's front section. It was the most powerful and fastest road-going Porsche until the introduction of the 918 Spyder in 2013.
The 911 Carrera Club Sport (CS) (option M637), 340 of which were produced worldwide from August 1987 to September 1989, is a reduced weight version of the standard Carrera that, with engine and suspension modifications, was purpose built for club racing
The 911 Speedster (option M503), a low-roof version of the Cabriolet which was evocative of the Porsche 356 Speedster of the 1950s, was produced in limited numbers (2,104) starting in January 1989 until July 1989 as both a narrow body car and a Turbo-look. The narrow version was produced only 171 times.
