2019-2023 BMW 3 Series (G20)
The G20 3 Series is the default choice for European buyers who want a genuinely engaging used saloon without stepping up to a still-pricey 5 Series.
Read the product overview
It has depreciated enough that a clean 320d now sits within reach of buyers cross-shopping a loaded Octavia, and the diesel's effortless motorway pace and 50-plus-mpg economy explain why it remains the volume seller on AutoScout24 and mobile.de. The honest counterweight is the cost of German ownership out of warranty: tyres, brakes, and any electronics fault all run higher than the mainstream cars on this list, so the smart buy is a 2020-2023 example with documented BMW service history and, ideally, time left on cover. Petrol 320i and the brisk M340i hold value firmer than the four-cylinder diesel, which softens most through winter. Buy on history, not on price alone.

How we assess prices
We use in-stock offers checked within 72 hours. Scores compare the current offer with that retailer’s observations from the last 90 days, requiring at least 14 observed days and a price from about 30 days ago. Suspect records withhold the score. Retailer conditions and prices can change.
