‘74 Duster 360 4M
Oh, I like that! Can I use that on my wife?Find out the difference in price between what you will get for that and a Scat/SRT. Since this car is paid off, save that payment for the amount of time you would be making it if you "upgrade". Take that chunk of cash and do something with it, even if it is supercharge the car you have.
Edit - Hmmm...that sounds funny. Can I use that argument with my wife to fund mods to my car?
Sounds like I am trying to upgrade my wife, who is irreplaceable to me.
