Used Mercedes-Benz GL-Class (2006 - 2012) Costs

Review by David Ross on
Last Updated: 30 Oct 2012
The Mercedes-Benz GL-Class is the car that some buyers may have been waiting many years for. It's a proper 4x4 with seven-seat practicality and yet has an interior that matches any of the company's saloons for comfort and style.

Running costs

Mercedes-Benz GL-Class running costs aren't great. Residuals - as a percentage - are pretty good, but in real terms, you could still be losing tens of thousands of pounds if you buy new. Going for a used or nearly-new model will save you money but running costs are still fairly high with tyres being especially expensive. The 320 CDI is the most economical but barely averages 29mpg and with a 100-litre tank - one of the biggest around - fill-ups are expensive.

It falls into the top insurance groups and Mercedes-Benz servicing is pricey.
