Possible 1st time Saab owner

[waynedear]

My boss is interested in a bike I have for sale, he has a 2008 9-3 cabby 1.9 in white.
Drove past him the other day and ‘jokingly’ said I’d swap the bike for the Saab… he asked if I was serious, I think I may be.
He said it needs work, apparently and I know no more details it need a roof motor and something to do with the aerial as they got flooded ???
Car has done 125k, decent mot, engine rebuilt after waterpump seized ( I know that feeling my Alfa gt did the same)
Anyone shed any light on the roof issues ?
