I replaced mine last year , mine was 55000 miles , 2 owners , no rust , body work in very good condition , interior was like new , got £1500 for it which wasn't to bad tbh. The first person that came to look at it bought it straight away and didn't even haggle.
mat they are slow lol, and if you drive like me , town drive , a bit of caining now and again you will see an average return of 220/230 miles per tank which is shocking . Parts are super expensive if you want to use genuine so everything that I had problems with either got uprated or a good quality part like Bosch got used.

major problems are

rusty wheel arches

rusty sills get the waxed straight away

major rust behind the rear wheel well liner where the boot floor joins the wheel tubs , you can sometimes see this when you pull the interior out of the boot , it starts under the sealant where the panels join

front subframes going really rusty and falling apart

the alloys are shocking and will Defo need a pro job done if they haven't already been refurbed.

lambda sensors without a doubt he will have trouble with ford want £280 per sensor so I used a Bosch direct replacement that comes with the ford plug be careful there's the universal one which you have to cut the plug off etc

clutch master cylinder again will Defo go at some point , tip get the top of your trainer and rub it up and down the back of the pedal mine was covered in fluid but non on the carpet

possible radiator if he drives it hard like I did

spark plugs

leads

coilpacks

imrc I never had a problem

imrc lever snapping

thermostat leaking again at some point he will have a problem

throttle body always sticking because of reburning oil from breather system , just clean , but it can make you throttle pedal stick open like it did with me.

rear engine mount knocking due to worn out bush

cats just crumbling away and breaking up

the list is endless

the first mod is the imrc lever = billet one from pumaspeed take 10 mins to fit , if it breaks your looking at £600 for a new genuine item
coilpack = msd coilpack and leads again from pumaspeed
plugs = denso iridium
lambdas = Bosch
thermostat = cfm early zetec style solid Bakelite thermostat housing only found on American car with extra sensor bung delete which always leaks even if you buy a new genuine bung and washer from ford , also comes with 10 degree lower stat as they run very hot.
Throttle body = clean or cfm large 76mm billet throttle body and I'd does make a difference
air filter = close system only or fit a k and n filter in the original air box , tip remove the side snorkel on the air box and it sounds like a really good induction kit , it really does change the noise of the car
everything else as and when it fails lol

hope this helps mat

cheers paul
