Probably continue the weight saving exercise of letting them rust even more

my Audi A4 failed it's MOT at the weekend.
The sti tax is £430 and due this month. Sti due it's MOT at the beginning of next month and the rear wheel arches are rusty again. Only go them welded about 2-3 years ago. Clearly did a poor job. So I'm guessing it's going to fail and I'll get another expensive trip to the body shop although it will be a different one this time. Still need to get the wheels refurbished. Needs new suspension again as the bilstein B14s are knocking.
The Hyundai i30 is working currently as the daily banger. Couldn't care less about it. Might change the oil when the weather gets better. Steering is knocking when I turn on the spot. As long as the wheels don't fall off it's fine.
Might go to the meet at ocuk. Other than that it will be driving to work and back.
If my garage was actually water tight I'd sawn the sti and sort a load of things myself but every time it rains heavily it turns into a swimming pool.
