But NAAMSA said new passenger car sales fell 4% month on month in November, compared to 30 750 in the previous month of October.

NAAMSA said new vehicle exports rose to their highest monthly total for the year with export sales increasing 24.2% to 28 550 from 22 985.
Aggregate export sales reflected further gains as manufacturers' output recovered from the loss of production due to industrial action experienced during the months of August and September of 2010.
The decline in interest rates over the past two years, improved new vehicle affordability, further gradual improvement in finance approval rates, pent up replacement demand and new model introductions should continue to support new vehicle sales going forward, NAAMSA said.
New vehicle sales over the medium term would remain a function of the performance of the domestic economy and, in the case of export sales, the sustainability of the recovery in the global economy.
