Hey everyone, there's this used DA9 for sale (should be able to get it for <$1000, no rego or RWC), went to inspect it today and there's a lot of (what looks like) oil under the hood. Any ideas what's wrong/what will be required to fix?







Some other (comparatively) minor things:

There's a pic of what looks like rusty welding after the.. catalytic converter?



The rear, right disk rotor seems badly rusted, though the others all look fine.



Also one of the rear windscreen, there's quite a large gap between the windscreen and the roof panel, looks much worse in real life. However, from the interior you can't even see it.



And lastly, there's one of the underside of the car, if you look closely you'll see that the panel thingy on the left of the picture is hanging significantly lower than the right, seems like it was bent or something.



The number plate is also crinkled and there's some issues with the paint work on the bumper, might be related to the underside issues... might these be a problem down the road?

One more thing: the passenger door's lock is broken, and the door is stuck locked. Any ideas?

Let me know if the pictures are too big..

Do you think it's worth buying? Thanks in advance!
