Hi guys,
Been out and took some photos of das auto.
It doesn't seem to be too bad (I've certainly seen a shed load worse in college) but remembering my goal of keeping this car for a long, long time should I get it seen to now or can it wait?
UNDERNEATH#1. Rust at the beginning of the chassis leg. Similar on both sides hence I only took a pic of the drivers' side

#2. Sill rust. This piece is about 12" along the sill from front backwards and then it stops and goes to silver metal

#3. Where the chassis rail meets the jacking point
BODYWORK#4. I hate this wheel arch! I've had it fixed once and now it's come back

#5. Inside the boot behind the wing (last pic). I'm presuming that the rusty wheel arch and this part here are all one piece thus I can get a new wing welded in and tarted up and that will be that? Or like usual have I missed something?

#6. Rear passenger door.

#7. One piece of rust rear passenger inner body panel (where door covers when shut). Would this be deep or not bearing in mind it's not bubbling or spread since I got the car 5 years ago?

SO. What's the verdict (other than new car, STEMO

). I'm thinking save up and have the under-car rust repaired and then blast it all with underseal. Then save up (again

) and get a new wing (rear drivers' side) welded in and have that other body work done as well.
As said I want to keep this car for ages so any advice would be greatly appreciated.
