Classic venture capitalism.
The buyers get their money out by highly leveraging the company i.e.the company borrowing repays them.
They then put lip stick on the pig & sell it on.
I suspect they expected the US CX sales sooner & now are struggling.
If they can't met the debt covenants which are usually ratios like NWC vs sales then the interest will increase.
The problem is of course with a handmade car you can't cut labour costs easily unless you move away from the handbuilt bit in many areas (as they are doing).
I know they bought back the site & I guess sale & leaseback might be a short term debt funding option.
