according to my handbook and annex, the Free standing weight in driving order for a 150bhp 1.9 diesel is 1368kg against 1489 for the 4wd version.
however, the 4wd has a bigger tank..
not sure how reliable this information is though, as the weights differ from the UK manual to my dutch one, and the dutch annex i have too..
so i'm guessing around 100kg
