I'd go the 3.7.
If fuel economy was the main factor, you wouldn't have bought the XR8!!!
If you went with the 3.45, you would always wonder how would the 3.7's go.

I wouldn't go lower than 3.45 in a 5 speed manual, unless you regularly come across beer trucks that need pulling off cliffs.

Two things: 1) 3.9 ratio gears are not available in M86.
2)Off the line, a BA V8 5 speed manual with 3.9 would be the same as an AU XR8 T5 with 4.46 diff gears.
