First off let me introduce myself;
I'm Jamie, 18, from Oakham, Leicestershire and have recently (stupidly) traded my 59 plate Fiesta for a 56 plate

. It so appears that the 'trader' has sold me a dud and that I'm going to have alot of work to do to bring it up to scratch. After paying £4800 for the car and £3800 for the insurance I don't have alot of money spare to bring it right, however every penny I earn is going on the car until it's perfect and I won't stop at nothing until it is. The clause comes that I have a limited mechanical knowledge and I need your kind help to do this!
I will list the various problems, probably add to the list as I go along, here goes nothing!
Problem 1) I have a very worrying rattle from the drivers side of the engine, the noise is most prominent when your head is near the front tyre, it seems to be coming from the various pulleys along the left hand side of the engine bay although I have no idea what it is and how it can be resolved. It doesn't change tone when you put strain on the alternator, it doesn't change tone when you move the steering wheel or put the air conditioning on. At the moment it sounds more like a diesel engine, the noise occurs when idleing and gets faster as you increase the revs.
Problem 2) Upon buying the car another problem I found is that the handbrake didn't work, this became obvious when I put it on and kept rolling down our drive. It turns out the rear right hand side caliper had seized up and with a good smack of a hammer and some WD40 it appears I've free'd it off. I believe its more to do with the cable as a pose to the brake itself and I was wondering how I go about replacing it. I.E. Where does it go when it disappears inside the car and how can I expose it
Problem 3) The engine gets up to 90mph very quickly, however it goes flat after this and takes along time to progress further, the car feels very unstable compared to what I'm used too at this speed also and it's very wobbly in the corners. Is this normal

behaviour or should I be checking for something?
Problem 4) After replacing the power steering fluid by disconnecting the low pressure return and running it into a bucket whilst topping it up with fresh fluid a noise has developed but only when the steering is on full lock, it's a graunch sound. Is this something that can be resolved or should I not worry about it?
Problem 5) The front bumper clips have disintegrated (underneath) from the actual bumper itself, what it slides into is still in tact. How can I rectify this or would it require a new bumper as it's all one peice?
Problem 6) The front drivers side wingmirror is missing the bottom screw, don't suppose anyone knows what thread this is off the top of their head so I can seek a replacement?
Thanks in advance for your replies and I do very much appreciate your help, as I say, I haven't got alot of money to take it to a garage so any self diagnosing or fixes I can do myself will save me alot of trouble.
Regards,
Jamie
