Retailers were the only automotive stocks to hold steady in the first quarter, Automotive News Europe reported. The UK, the home market for most publicly held dealer groups, became Europe's largest and most resilient market in March. UK sales rose 3.4% in March, compared with an overall rise of 2.4% in the 17 west European countries. With 438,000 passenger car registrations in the month, the UK total was well ahead of Germany's 318,000.
