Looks like the owner definitely wanted shut of that one! Did it have any service history?
Looks like several jobs have been given little attention, nothing major, as Alex says that door is not normal!
TVA clean out should do the trick, clean the MAP sensor as well.
The 1.3 is not a very refined engine (quiet and sedate) its a noisy revvy little thing but TBH that's why most of us 1.3 owners love it to bits, I have often worried about Cylinder head gasket on mine as the older it gets, the more gurggly it sounds, but am unsure as to whether that actually is an issue or not.
The wiper could be old wiper blades if its getting stuck or maybe the symptom of a failing wiper motor, mine did that on the rear before stopping completely!
I am sorry that you haven't been lucky with your purchase, but all issues can be sorted out on this car with basic mechanical skills, most mechanics love the simplicity and their layout!
