Seems to be a popular choice on here at the moment! I've been looking for a decent Signum for ages, to the point of nearly giving up and getting something else. I was quite specific about what I wanted; 1.9 CDTi, <70k miles, manual, cloth interior, not silver, facelift model.. and within budget.
Luckily the perfect car appeared and I paid a deposit on it yesterday
Vauxhall Signum Elegance 1.9 CDTi (150)
Sat nav, cruise control etc
Very pleased, just need to wait a couple of weeks till I pick it up.
