help interpreting a balance sheet

I would guess the average sales price of their stock is £75-100K. It’s hard to tell what stock they own and what stock they are selling on behalf of a (typically) private client on a sale or return basis.

The sale price of the car is irrelevant. It's the profit that matters, and after costs - including the cost of committed capital, even in these low interest days - that is often much less than you might imagine.

Did you read the notes to the accounts? Does it mention anything in there?

No. As they're statutory accounts the notes are very brief and provide no real explanation as to what the business is up to.
