Its elongated shape offers space and practicality compared with a conventional hatch, without the bulk of an SUV, making it unusual in the used-car market. mycarcheck.com records 114 look-ups for this version, covering 24 distinct VINs: a useful snapshot, though not a huge sample. Average private-sale valuation is £600; recorded mileage averages 140,000 miles, with annual use around 9,000 miles. Cars show about five previous keepers on average, so check each vehicle’s history and condition.

It feels individual compared with a Vectra or Mondeo, but age and mileage make service records, running condition and vehicle checks important.
