A rebounding auto market helped dealers. European new-car registrations rose 5.7 percent to just under 15 million in 2015. The top 50 groups took 10.4 percent of those sales, up from 10.1 percent in 2014. The low share reflects the fact that many new cars are sold through family-owned operations with one or two outlets.
Average revenue for groups in the top 50 ranking increased 15 percent to 1.8 billion euros from 2014, ICDP calculated. Those in the top 10 increased their average revenue by 31 percent to 4.5 billion euros, while the middle-ranked players in positions 11 to 25 saw a 22 percent increase to 1.6 billion euros.
ICDP said the revenue gains are partly a reflection of the strength of the pound against the euro in recent years. Five of the 10 biggest dealer groups are based in the UK. Those gains are likely to recede following the pound's fall against the euro after the British voted to leave the EU.
