watch out for the peugeot engines in 307's and the like once they have a few miles on them the particulate filter system goes tits up on them sometimes lucky if it just needs cleaning and regenerating the filter but most times needs complete overhaul costing £1500-£2000grand most of the ones ive worked on have happened around 50,000 miles then every 50,000 after that too! shame because the engines themselves are really reliable, this goes for the small derv engined fords too as they are peugeot engines as well

personally i would go for golf or polo diesel
