Are you in the market for a brand new Opel Manta? Well if you are you need to be prepared to shell out over £40,000 to get your hands on this, possibly unique 97km (60 miles) from new time-warp car. At least it’s the top-of-the-range GSi (GTE in the UK) with full documentation. Reasons as to why the car have never been used are unclear, but for this kind of cash we’d expect it to have been properly maintained all the while it was laid up.

Price: €59,500 (£42,400)
