Welcome Welcome... If you see a white M with an "OFFSUIT" plate in Vegas say hi!
1. You may want to try to find a forum member or someone local who would like to trade rear trunks with you... That would be the least expensive way to go... A body shop can "SHAVE" your spoiler, fill in the holes...
Here is an example of the work that needs to be done though from my last car...

2. Hesitation as it gets into the 4K RPM mark?
3. Not too much on the performance side for this car unfortunatly... There are some people trying to change that though
Enjoy!
