Australia looks set to give its car sales record a shake following a 20 percent month-on-month rise in June, writes Mike Duffy. Buyers invaded showrooms and drove away 73,557 new cars and commercials - 12,239 more than the same month last year. This boosted January-June registrations to 375,076 units, 21,585 vehicles or 6.1 percent higher than the same period last year, the second highest result on record.
