What used Citroën C8 MPV will I get for my budget?
How much does it cost to run a Citroën C8 MPV?
The C8 is sold new for huge discounts below what is only a vaguely notional list price, so nearly new ones should be conspicuously cheap. However, be careful not to stump up too much for a one-year-old C8 or you'll pay the price in depreciation when you resell it.
Other than that, you should be able to pick up a used C8, run it and then sell it inexpensively.
