Petrol model yes, diesel, noo.
to add, turbo actuators,water pump/power steering separation, chain tensioner wear,aux belt pulley disintegration.
Did somebody mention dmf which clogs up the starter with fine dust..
To caveat that, I wouldn't buy a TD
CI, but if you can find the much lower tech TD
DI then you'll have fewer issues. I bought mine (2001 GhiaX hatchback) knowing the DMF was knackered for chump change with 75k on it. I had it because I needed something cheap to get me between Loughborough and London each week and then be parked on an east London backstreet.
Beyond the DMF (£750 but known when I bought the car), it cost me a battery, plus routine maintenance in 65k. The car had full leather, heated and electric, sunroof, cruise, climate etc etc. It wasn't refined but returned between 45 (winter) and 48 (summer) the whole time I had it. I only got rid of it when I started doing up my current house and needed something even bigger to put DIY materials in.
As others have said, they have their problems but I think the tinternet overexaggerates these when you consider just how many mondeos have rolled off the production line over the years. If you find a good one, they make very cheap (if somewhat unexciting) transport options.
