Call to pass on petrol price cuts

THE AA has joined calls for retailers to pass on a fall in the wholesale price of petrol to motorists. Pump prices have "barely budged" from the late summer high of just over 138p a litre despite a 2p-a-litre fall in the wholesale price of petrol a fortnight ago and a further 3p drop last week, according to the latest AA Fuel Price Report. Petrol averaged 132p at the start of the year, "and this is where it should be heading if the wholesale price collapse persists", the report said.

"We've very carefully built Buick back to a brand that has respect," GM North America President Mark Reuss told Automotive News.

Last-ever BMW M3 Coupe rolls off line

With only a shade over 16,000 examples produced for the worldwide market during its run, the first-generation BMW M3 wasn't built in significantly larger numbers than the Lamborghini Gallardo (13,059 cars by the end of the 2012 model year). And they were all coupes. The four-door M3 was introduced in 1994, two years after the second-generation coupe bowed, sat out the car's E46 run and then returned for the E90's run.
