C3 can have a proper TC auto box, and very nice it is too but rare as hens teeth, found in the top range petrol 1.6 SXi if my memory serves.

Citroens of this era can be superb little cars, or they can be a right PITA, i've known people who have taken small Citroens round the clock twice and swear by them, i know others who's only comment about them is swearing, i think they like all cars respond to good care and mechanical sympathy, where they differ from proper Japanese petrol cars is that even if neglected and abused the Japanese stuff will soldier on regardless.

Whilst i agree broadly with Galileo, if the Citroen is a known car with known care and history and is cheap enough it might be worth a punt (but do not buy the automated manual box designed by satan that Galileo refers to), but if its just a n other car on a dealers forecourt you would probablt be better off in a late Corolla or Yaris/Auris or Civic or Ceed.

+1 to the note, good legroom and headroom.
