S4 Foggy

Hi I am new to this forum and have the chance to get the use of my brother's S4 Foggy (number 68 he thinks) which he got new in Nov 2001, it has done about 600 miles and has had a new wiring loom and a few other things under warranty but has been sat in a steel box out side for about 6 years, I have had a licence for about 14 years but not ridden for about 8, can anyone tell me if there are certian things I would have to do to get this back on the road and do you think it's too much bike for me to start off on? thanks in advance for any replies (I'm in Gloucestershire) regards Ian
