Best used buy
BMW 4 Series
4 Series for sharper dynamics with clean BMW engine history; A5 when S tronic, quattro, and EA888/TDI evidence is stronger.
Both cars can be good used buys, but they are often bought emotionally. The better example is the one with clearer engine, gearbox, tire, and body evidence rather than the better badge or prettier spec.
Key differences
- BMW risk centers on cooling, oil leaks, timing-sensitive engines, and ZF service evidence.
- Audi risk centers on EA888/TDI generation, S tronic service, quattro assumptions, and oil behavior.
- The 4 Series usually feels more rear-drive and driver-focused.
- The A5 usually feels more refined and secure, especially in quattro form.
Buyer advice
- Choose the 4 Series if cold-start, leak, and gearbox checks are clean.
- Choose the A5 if engine code, S tronic, and quattro/Haldex records are stronger.
- Inspect body, tires, brakes, and modification history carefully on either car.
Red flags
- Timing rattle
- S tronic judder
- Coolant loss
- Oil consumption
- Cheap modifications
