Re: 147 diesel advice...
Mine is the same, 16v m-jet sticker on the boot, engine cover and the V5 document, 8v's just have a JTD sticker on the back (I think). The facelift models were uprated to 150bhp, pre-facelift 16v m-jet models are 140bhp. Exactly the same engine in both with different maps, there's a 170-180bhp model on the way which is exactly the same with a different map. If you cough up £250-£300 you can get your own map and raise any of them to to around the 190bhp mark witrh affecting service intervals or economy.
Pulled the stickers off mine, too much clutter on the boot IMO. They're lovely engines, drive beautifully, there's bags of power and you'll be up near 50mpg.
Good luck with the search
