I don't know. Maybe I am confused about something.
On today's circumstances, this motor is a steal.
Nearly new fiestas are 13k+ - there are almost no new cars coming in, and dealers are struggling to shift the stock they have already. A new order for a LC150 has a 18+ month wait.
The only reason someone's not picked this up already at this price is because you are not putting it in from of the wider audience.
Yes diesel price is concerning. Lez and ulez and euro4+ are a considerable pain in the ass. But so is reliability, space, ability and comfort. This feels like a looked after vehicle that would do another 10years.
