Well, ignoring the front-drive underpinnings and 406 interior (though I've always harboured an inexplicable affection for the 406 dash and squishy leather upholstery, however rubbish it might actually be), not a lot, really.
And unlike more modern coupes from mainstream manufacturers (the forthcoming Toyobaru BRZ/FT-86 being a notable exception), turn-of-the-Millennium two-doors were what you might call proper coupes, rather than the rakish hatchbacked pseudo-coupes that the likes of VW (Scirocco), Renault (Megane) and Vauxhall (GTC) have been churning out of late.
Still, that roaring-lion badge is probably going to put off as many people as it attracts (although the allure of Pininfarina might mitigate that somewhat, but if you want a sleek, comfy and moderately luxurious cruiser then you might well fall for the svelte Pug's myriad charms.
This one has done a thoroughly average 128k miles, but it looks in pretty decent nick (well, it does in the photos...) and has a whisker of tax and moderate amounts of ticket left on it. You do get plenty of kit with this one, too, including leather, heated seats, air-con and a JBL six-cd changer system.
Kudos to PHer ninos for the cracking spot...

'X' 2000 Peugeot 406 Coupe 3.0 V6 in Metallic Blue with superb Black Leather Interior, this is a fine example of this soon to be rare sporty classic.
