OK, so this last week went out and looked at some cars and took the boys booster seats with me to see what the fit in I have narrowed down my chose to 2 cars but I may not sure what route I want to go.   
So here is what I am looking at first up is a black 05 Impala SS

Car is fully loaded has the series II supercharged 3800 260 hp from what I have seen on the web. Only think that I saw wrong with it is the wing was hit with something.    
Pros. 
Leather  
back seat is larger then the Magnum 
Stronger aftermarket (not that I will be doing a lot mod wise anyway).   
Cons  
tan Interior  
FWD         
Second car is black 05 Dodge Magnum SXT

Car is fully loaded as well minus Navi. Has the 3.5 liter v-6 makes like 250 hp.    
Pros. 
really like the styling of the car. 
Leather (dark gray). 
less miles then the Impala 
cheaper then Impala 
RWD   
Cons 
no supercharger. 
wife doesn't like RWD. 
no aftermarket support. (not a big issue but this.) 
rear seat is smaller then the Impala.
