5 Series.
The benchmark executive saloon.

The 5 Series is BMW's mid-size saloon, in continuous production since 1972. Successive generations — E39, E60, F10 and G30 — set the executive-class standard. The engine range spans inline-sixes, V8s and diesels, with the M5 as the apex, running a V8 or V10 depending on generation. Drive is classically to the rear axle, with optional xDrive on newer years. The 5 Series surfaces regularly at Japanese auctions, often in high specification.
