e46 m3 or 650i

[ju6121]

After owning my e46 m3 convertible for 6 months now I am looking at moving on to something different and was looking at a 650i convertible. Has anyone gone from an m3 to a 650i? In particular what is practility and driveabilty like compared to an m3? Also does the engine sound as amazing as the m3 with roof down?

do you mean the 650 is much cheaper to run than the m3 or the other way round?

[ju6121]

is it worth paying extra for the 650 or is the 645 better value in terms of pace and economy?
