RUNNING COSTS

With expensive luxury cars, servicing can be a big part of the running costs. Mercedes’ £41-per-month pack comes to £1,476 over three years. The LC undercuts this at £1,285.

DEPRECIATION The newer LC is predicted to keep its value better here. Our experts expect the SL to retain 48 per cent, losing £40,055 over three years, with the Lexus holding 51.5 per cent; a loss of £37,118.
