The Orion is definitely an overlooked modern classics and despite numbers dwindling values aren't rising as much as you'd expect. On paper, a low mileage, two-owner car would be at the top of the price spectrum (about £1700) for non-performance examples. However, it depends entirely on the condition of the car and its service history - if the car hasn't moved in 20 years and is rotten then it's probably only worth about £500 as a project.
