Reliable fuel consumption data for comparison purposes is not available for this model.

The GTC isn't going to be massively expensive to run. An economical set of petrol and diesel engines will keep fuel bills down, while CO2 emissions are kept reasonable too which will keep tax bills in check. Vauxhall isn't the most expensive firm when it comes to servicing, yet because it'll need doing every year the costs may mount up when comparing to other manufacturers.

We expect the GTC to hold its value fairly well thanks to its sporty, desirable nature.

The green vote is for the 1.7-litre diesel engine, which emits 119g/km CO2 and returns 62.8mpg on the combined cycle with both power outputs. However, the impending ecoFLEX model is set to change that, with even lower emissions and better fuel economy expected.

Typically there aren’t many issues with Vauxhall reliability. There haven’t been any major recalls, and the engines have been proven reliable in other platforms. Many of the interior parts are shared by other cars in the Vauxhall range and so should prove fairly hard-wearing. The car does have a ‘well-screwed-together’ feel to it, so we don’t anticipate many problems.
