Hi Andy,
First a warm welcome to THE real T 300 club, here's hoping that you're feeling allright in this community.
Although i must admit that i'm Dutch, i feel at home here.
To my opinion a asking price of 2700 euro's is quiet a lot of money to my point of view for a '95 Trophy 900 but as you wrote, it only did 18.000 km. When it is a very nice and good bike it might be worth it.
Is there a pannier set aswell to go with the bike? That alone is worth a few hundred.
Anyway, good luck with your "new" Triumph, whatever model you decide on.
Are you living in Germany at the moment?
Kind regards,
Koos
