Random crack. Any idea on cost?

Noticed this the other week. Car was dirty when I first noticed It, no marks on the dirt so no sign of any impact. Guessing it's a previous repair that's given up. It has about a 1mm height difference, maybe less. Any idea what I should be expecting to pay to have this done?

That's not the only crack. If you look closely you'll see there's a couple of others.

There also appears to be misalignment at the lower edge of the join between the panels.

Impossible to say what's actually going on there without inspection although my suspicion is an old repair failing & the filler is coming away from the panel. It's what's under the filler that's the problem & I wonder if there's a split in the panel that's just been bridged with filler.

Needs to be seen to get an idea of cost so I'd suggest visiting a couple of bodyshops local to you.
