Unsure on the front of the Twingo but i used to dislike the front end of the 200, so i'm sure i will like it in time. I haven't seen one on the road either so thats always a good thing, unique!
172 :) Plenty of room in the boot for the dog. Our german shepherd/husky fits in there fine.
I also like the MG ZR's. But it looks like you've settled on a 307 now.
