Very likeable cars, especially with the excellent PSA diesels - my dad had a couple. 306 was very under-rated - good to drive and well thought out - one of the last good Peugeots. The Sedan added decent boot space compared to the small hatchback's load area, but was a poor seller in UK.

306 introduced in March 1993, Sedan followed later (October 1994 in the UK) and this one is from before the facelift introduced in May 1997.

My next car, I hope! :3
But ... I'm not sure what year it is, mid 90s, late 90s? 1997? 1998?
1999? damn!
