Are you thinking of getting a used sports car? Then the BMW Z3 is a good option. On AutoUncle, you can find 121 used BMW Z3s for sale in the UK compiled from different dealership websites and online marketplaces.
A used BMW Z3 costs between £2,490 for the cheapest variant and £7,950 for the most expensive model.
A pre-owned BMW Z3 can cost different relying on mainly five factors: the year of the car, engine size and power, fuel economy of the car, how much the car's odometer reads together with equipment.
For instance, a younger model with less miles on the odometer, or more luxurious models with more potent engines will typically cost more than a used model with many kilometres on the odometer and in a simple equipment variant.
When looking for the best car deal for a used BMW Z3, it is essential that you exclusively compare with the prices of cars with the same engine and equipment. If not, you may come to a wrong decision on which car to acquire.
Petrol ranks as the top fuel type for the BMW Z3.
BMW Z3 is available with the following fuel types:
Before you finalize your choice of fuel type, we suggest thoroughly evaluating your driving habits. Is your car mainly for commuting, or do you tend to take it on long road trips? On average, how many miles do you drive per week?
If you primarily drive short distances, electric, plug-in hybrid or petrol is typically a good fit. For longer commutes, a newer electric car is a good alternative - especially with access to charging. 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. If you often drive long distances and can't charge, diesel can still be a viable option. Note that diesel engines with significant emissions have faced entry bans in cities across numerous countries.
The BMW Z3 comes in two different body types; cabriolet and sedan, with the cabriolet being the preferred option. If you want to add a new dimension to the driving experiences, then a cabrio or a convertible is the perfect solution. Most cabrio models can be driven year-round these days, thanks to their excellent hoods and weather gear. To strengthen the chassis to make up for the lack of roof, thickener is applied underneath the car, which means that convertibles are often heavier than normal cars.
Several vehicles that are similar to the BMW Z3 are available.
