Well, I think 100 pounds is a very good price, but it´s only my opinion. Those crazy prices are the reason I did my own set of led indicators, the whole cost of the set with electronic flasher are a minimal fraction of an used original set and drain less power from batteries, if somebody wants the links of the parts I´ll give them at once, I like maintain my C5 as original as I can but I can´t pay so high prices for parts, and I use the C5 as a daily commuter so I need to replace parts frequently to keep it reliable and safe, and if I need alternative sources of parts I think I´ll use them.
