Very sad news, think she is the only person to be involved in all eras of the show since the return in 2002, she did the famous Nurburgring in a van in the Clarkson era and did the UK v Germany Top Gear showdown then presented features in the Evans, LeBlanc and I think she did a feature with Chris Harris in the current era and of course she presented German Top Gear.
RIP Sabine, one taken far too soon.
