exec - pro
- more interior space (feels more luxurious)

exec - cons
- longer (more parking space, harder maneuverability)
- heavier (slower acceleration, more stress to brakes and tyres - although very minimal)
- parts harder to find (rear doors, windows, door panels)

but now, i'd take exec over normal sedan. hehe..
put in turbo engine and change to bigger/better brake set..
