I'm just curious as too people's opinions about the both of them, I'm not in the market for either at the time. I've driven an E90 M3 and wasn't blood away, but I reckon if I had one for a weekend that would most likely change.

Have to agree though, I reckon the S65 V8 will be highly regarded in the future as it is now.

You can't beat a high revving V8 and I would imagine it's probably a better engine then the M5 variant
