Are you looking for a used Vauxhall Astra GTC?

Are you thinking of purchasing a used medium sized family car? Then the Vauxhall Astra GTC is a good option. AutoUncle has 374 used Vauxhall Astra GTCs for sale in UK sourced from numerous dealership websites and online marketplaces.

How much does a used Vauxhall Astra GTC go for?

Currently, the prices for a pre-owned Vauxhall Astra GTC start at £2,295 and go up to £10,995.

The used car price for the British car is influenced by five main factors: manufacturing year, engine size and performance, fuel efficiency of the car, the car's mileage together with the level of equipment in the car.

For example, a newer model with low mileage or a premium version equipped with a high-performance engine generally demands a higher price than a used model with many kilometres on the odometer and in a simple equipment variant.

What equipment variants is the Vauxhall Astra GTC available in?

The following equipment variants are the most populare ones for the Vauxhall Astra GTC:

In order to find the best sale price, it is important only comparing the deals of cars with the same equipment variant and engine size. Otherwise, you might end up reaching a wrong conclusion on which car to purchase.

What fuel types are available for the Vauxhall Astra GTC?

Petrol ranks as the top fuel type for the Vauxhall Astra GTC.

Available fuel options:

When deciding on a fuel type, your driving habits should be a key consideration. What's the average distance you drive weekly? Do you have a preference for shorter trips, or do you usually drive long distances?

If your trips are mostly short, electric, plug-in hybrid or petrol may make the most sense. For daily long-distance driving, the electric car is often ideal - especially with a charger at home or at work. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. Diesel cars can still make sense if you drive very far and don't have access to charging. Take into account that several countries restrict high-emission diesel engines from their city zones.

In which body types are the Vauxhall Astra GTC available?

With the coupe being the more popular choice, the Vauxhall Astra GTC is offered in both coupe and hatchback body styles in the UK. A coupe boasts a body design that accentuates style and offers a sportier driving experience. Its chassis is usually more rigid and robust compared to a saloon or SUV. This car is ideal for those without children and those who prefer travelling with fewer items. Typically, coupés come with a higher price tag than their corresponding saloon or hatchback counterparts.
