Need a little help

Our local dealer has a Mopar 10 sitting on their lot i would like to have in my collection. I currently have 3 SRTs in my shop and a IE that should be hitting the ground in 2 weeks. So what i was thinking of doing was trading in the 2009 torred on it. The torred has less than 400kms on it and about another $2000 invested in aftermarket accessories on it. So therefore i would be getting less on the mopar 10 but stepping up one year and it is also a limited edition. The dealership is asking $4000 diff and this is where i have a bit trouble making the choice. The problem is what i am giving up to get the mopar 10. Any thoughts that might help would be appreciated. Now i understand the meaning of being caught between a rock and a hard spot.patchs:notallthere:
