The Cadillac brand is relatively new to the UK which makes predictions about its future residuals less certain, but it is not expected to perform any better than rivals from Saab and Alfa Romeo. A top spec diesel engined model would be the one to hold its value best. Servicing should be relatively affordable but bear in mind that you may face a lengthy journey to your nearest Cadillac dealer.

The BLS is quite a polluting model and with an average of 205g/km CO2 across the line-up, its emissions are a touch high. The greenest model is the actually the more powerful 1.9-litre diesel with 180bhp – it emits 151g/km of CO2 and returns 50mpg.

The Saab 9-3 which the BLS is based on has proved a reliable car on the whole with only a few minor problems on early cars. All the engines in the line-up have been well-proven in other GM cars.
