What is the used car price of the Vauxhall Astra GTC?

A used Vauxhall Astra GTC costs between £2,295 for the cheapest variant and £10,995 for the most expensive model.

The used car price for a Vauxhall Astra GTC can differ a lot and depends on five primary factors: what year the car is from, engine size and performance, fuel efficiency, how many miles the car has travelled and equipment level.

For instance, a more recent model with lower mileage, or a luxury edition with a robust engine, usually garners a premium price than a car from an older model year, with higher mileage and no optional extras.

What versions of the Vauxhall Astra GTC are available based on equipment?

In order to find the best sale price, it is essential only comparing the deals of cars with the same engine and equipment. Otherwise, you could come to a wrong conclusion on which car to buy.

Types of fuel:

Your driving behavior is an important aspect to consider when selecting a fuel type. Are your driving routes predominantly in urban areas or on highways and motorways? What is your average weekly mileage?

Electric cars, plug-in hybrids and petrol are great for short distances. For long daily driving, electric cars are a strong choice if you can charge. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. In a few cases with long journeys and limited charging infrastructure, diesel can be a practical solution. It's important to consider that in some countries, diesel engines with high emissions are prohibited from entering cities.
