Each region quoted in its local currency — independent market readings, not FX conversions
Once cheap and feared for its running costs, the E60 M5 has moved into modern-classic territory on the strength of its unrepeatable V10. Manual saloons lead the US market, the Touring is the rarity prize in Europe, and sorted cars with documented major service history (rod bearings, SMG pump, VANOS) trade well clear of neglected ones. Condition and receipts are everything here.
