Thanks for the welcome Gilles, indeed I use autoscout a lot, in conjunction with "Le Parking". Le parking has the advantage of also providing the date when the car sale was published.
For the "built after", I'm even more restrictive:
- 4/4 as of Sigma engine +/-2008
- Plus 4 as of Duratec engine +/- 2004-2005
- Roadster as of 2004-2005
