Are you considering getting a used sports car? Then the BMW 123 is an excellent choice. AutoUncle present 77 options sourced from various dealership websites and online marketplaces.
A used BMW 123 costs between £28,990 for the cheapest variant and £35,000 for the most expensive model.
The used car price for a BMW 123 is dictated by five primary factors: the year of the car, engine capacity and performance, the car's fuel efficiency, mileage and the level of equipment in the car.
As an example, a newer model with fewer miles covered, or a high-end version boasting a potent engine, often fetches a top-tier price than a car from an older model year, with higher mileage and no optional extras.
The BMW 123 is only available in one trim level, the BMW 123 M Sport.
As you considers the cost of a used BMW 123, it's fundamental to evaluate vehicles with equivalent engines and accessories. If you don't, you might draw an inaccurate conclusion about which car to acquire.
For the BMW 123, petrol is the most favored fuel.
BMW 123 fuel types compared:
We urge you to take your driving habits into account before settling on a specific fuel type. How far do you usually drive in a standard week? Are your trips more often short ones, or do you tend to travel over long distances?
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. Diesel cars may still be relevant in some cases with very long journeys and lack of charging options. It's important to consider that in some countries, diesel engines with high emissions are prohibited from entering cities.
On AutoUncle, the BMW 123 is exclusively offered in the hatchback body style. Hatchbacks are versatile compact cars that meld superb driving dynamics with a surprisingly spacious interior. Their popularity soars among city dwellers, given their fuel efficiency and ease of parking.
The BMW 123 faces stiff competition within its segment.
