looking to buy a m6 in the 03 to 05 range. any pros or cons to which year is more reliable? is it smart to buy one with upper 90k miles? thanks

Not V6

V6 has pre-cat issues that can cause engine failure. Y-pipe is also poor.
Don't know about the 4 banger.

4 banger is more removals than the v6 because it's prone to the issues above. But on the con side it is much slower...
