What should I be paying?
Merc’s residual values are usually strong, and the CLA shouldn’t be any different. Expect to lose about half the value over a three-year period. But make sure you go for the dual clutch ‘box – second hand Mercs with a manual are much harder to shift. In terms of fuel economy, the CLA is on a par with the few rivals it has. The diesel will be the better seller in the UK, and when you look at the fuel economy, you can understand why: 67.3mpg and 109g/km. Mini-CLS looks but not CLS thirst, which is likely to be a key part of its appeal.
