Other options include...

Borrow 2 wheels for the MOT, search around for some 2nd hand struts (sure I have 2 somewhere), new front wing will be about £17 and it will pass the mot without being painted (get that done later). Get a garage or mate to fit it for you and also ask him to do the other welding jobs at the same time. Disc's and Pads thats a safety issue so get them replaced. 1 hour job at the most and parts from a motorfactors and shouldnt cost more than £80.

Replace the tyres once through the MOT, paint the wing, and keep on top of the car all year then next MOT time you won't have any nasty surprises.
