I'm not so sure the SRT4 will be cost saving. Look at insurance. I pay less for insurance on my leased crossfire than I did on my 99 eclipse turbo. I'm under 25, own a house, and had 3 vehicles. Multi car discount is the only thing that helped.

I'm now down to one car and a bike and pay less on the crossfire than I did on the eclipse alone. By 40 a month!

If it was me, I'd get something I wouldn't even have the option to modify. You think you are spending money on the crossfire, wait til you get into performance upgrades on the SRT4.
