Thank you guys!!!
I brought home my Fiesta last thursday, at the moment i've driven it for 300 km more or less...what a car!!!

It's really a pleasure to drive! I love the engine and the gear ratio is perfect, you Always have a lot of torque. I like it so much outside and inside, the interior is really beautiful and the sport sits are very comfortable too. The only thing that i don't like is the steering wheel that it's too fat for me. I'd like to install an aftermarket steering wheel but you could have insurance problem putting a steering wheel without airbag...but i could change it anyway.
The handling is very good too, anyway i'd like to install a lowering kit in the future, probably a 40/40 one. And a set of alloys for summer tyres, now i have winter tyres on steel rims with plastic covers.
There are few things to fix :
_the auxiliary belt is noisy, at first i thought it was the power steering pump, i changed the oil but the noise didn't go away....so i think it could be a pulley bearing, maybe the idler pulley.
_ brakes are very worn, i'll have to replace pads and disks. I'd like to make a disk conversion on the rear, do you know if it's possible? I have a set of my brother's 206 RC with calipers (pcd is the same).....but i have to check for the measurements....the 206 RC has 17" wheels, my Fiesta has 14".
_ i think that the clutch needs a bit of adjustment because when you shift quick, once you push the throttle again it's like you have the clutch a bit down....not so good. I think it needs only an adjustment because the clutch doesn't work like a worn out one.
_ the coolant temperature gauge doesn't work, i think it could be the sensor on the thermostat housing. Am i right? Often on E30s you fix the problem this way.
_ ....and i need a brand new radio with usb port, now the car has a '70s head unit

It would be nice on a MK1 or 2 not on the MK3.
