The facelifted BMW M5 Touring E61 LCI remains a total outlier from 2007 onward: a family estate, but with a naturally aspirated `V10`, `507 hp` and `SMG III`. Against a regular 5 Series Touring, the gap is total; against other fast large estates of its era, it keeps an almost irrational singularity. It is also rare and produced in very small numbers, which means its value depends directly on the quality of its mechanical follow-up.
At the centre sits the `S85 5.0 V10` in facelift form, with all that implies: rod bearings, throttle actuators, ignition, cooling, lubrication and a very serious reading of the `SMG III`. The estate adds its own concerns: more rear mass, tailgate hardware and wiring, sealing, daily-life wear and extra thermal load on a car that can carry volume at very high speed. A good E61 LCI Touring is unique. A bad one combines M5 E60 costs with the side issues of a large, complex estate.
