BMW has recently overhauled its sedan lineup, with redesigns to the 5-Series and 7-Series being generally well-received. However, the aging 3-Series has been in need of a change for some time, and it appears that update will be sooner rather than later.

According to a report from BMW Blog, the German automaker plans to end production of the current 3-Series in October, in preparation for a Spring 2012 launch of the new sedan. The report hasn't yet seen an official comment from BMW, but all signs point to it being true. Spy shots have already captured several test models of the new 3-Series, and the spring launch window would give BMW a chance to debut the model at the Frankfurt Auto Show on its home turf.

In addition, the automaker tends to overhaul its models seven years after their introduction, with rare exceptions – and the current generation of the 3-Series turns seven next spring.

Drivers interested in purchasing a BMW 3-Series may want to hold off for the time being, as it appears the next model is just over the horizon. On the other hand, the introduction of a new generation always leads to an influx of used BMWs, where smart shoppers can score some great savings if they don't mind a few clicks on the odometer.
