Interested in finding a great deal on the popular MG MG3?

Are you considering getting a used small car? The MG MG3 is a great pick. AutoUncle presents an impressive 1,718 options in the UK collected from various dealership websites and online marketplaces.

What is the cost of a pre-owned MG MG3?

Currently, the prices for a pre-owned MG MG3 start at £5,499 and go up to £19,995.

For instance, a model that is younger with a lower number on the odometer, or more luxurious models with more potent engines will generally cost more than a car from an older model year, with higher mileage and no optional extras.

How many equipment options are there for the MG MG3?

The most popular equipment variants for the MG MG3 are:

  • MG MG3 Trophy: Right now you will find 545 cars for sale at an average price of £17,502

  • MG MG3 Luxury: 1 car for sale at an average price of £3,290

When assessing the price of a used MG MG3, it's essential to examine vehicles that have the same engines and features. Otherwise, you might draw an inaccurate conclusion about which car to acquire.

What are the fuel options for the MG MG3?

  • MG MG3 hybrid: Currently there is 10 cars available on AutoUncle with an average price of £23,801

In the process of choosing a fuel type, don’t overlook the importance of your driving habits. On a regular week, how far do you drive? Do you engage in many brief trips, or are your drives generally longer in distance?

For short journeys, electric cars, plug-in hybrids or petrol cars are obvious choices. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work.
