Just watched a brilliant doco about Pikes Peak on Foxtel. No Alfas but the video of Ari Vatanen's 1988 run in a Peugeot 405 is worth a look. Would be the perfect place for a 4C and Giulia to prove their mettle.
Of course Loeb's 2013 record run isn't bad viewing either:
Note the idiot running across the track about 48s into the video.
Vartanen's is dirtier.
Agreed, the Flying Finn's run is by far the best. Sealing the track has really taken some of the edge off.
Mind you, there have still been a few nasty offs since then.
