Porker993, the discs look messy in that shot from the cleaning process, but after using the brakes they look fine again.
Not planning on going anywhere near concours as my car OCD is bad enough as it is, think I'd be too obsessive to go down the competition route. [&:]
993C4S_KO, definitely driving the car but it's really a weekend/holiday/event/project car rather than a daily driver.
JB 3.2, I followed instruction from a guy called Jackal who is on the 911uk forum. It was relatively hard work with fifteen years worth of tar and grime under the arches, taking two or three hours on each arch for example. But the results are worth it and with the appropriate chemicals the process become so much easier.
You can follow Jackal's guides for detailing/upgrading/maintaining a 993 here (go to 993 detail in the left hand panel for the guide to cleaning the arches):

For the engine bay I used a combination of engine degreaser, Tarminator for tar/gunk removal, Aerospace 303 and then Megiuars Elite Trim Detailer. The bearing that controls the speed of the pulleys on the front of the engine fan packed up and needed replacing. The fan housing needing taking apart for this so I had they guys at Tognola clean up and lacquer the fan and spray the fan housing satin black. Painting the fan housing black really helped to clean up the engine bay.
