No comparable data available. The market is too small. Some obvious things though - big French cars in particular depreciate quicker than they drive. Mondeo sized petrol engined cars 1.8 and above loose quite a bit of value over 2 or 3 years - BMW's less so than Citroen for example.
If you want to minimise depreciation on a newish car, I'd suggest a Mini Cooper. If you need space a mini MPV (Scenic or Focus C-Max) especially in diesel engined form will retain reasonable value. In a bigger saloon a used Merc. E class CDI is good.
Which ever you choose, depreciation is a sore reality. The trick is to minimise it, within reason.
