Cadillac: $0.1059
VW: $0.0474
Dfference: 5.85 cents/mile
$5000 / $0.0585 = 85470 miles
If you pay $5000 for the VW it'll take 85k miles (7 years if you drive 12k mi/yr) to pay for itself with the difference in gas costs. Of course if you sell the Caddy that'll help, but buying a new car to save on gas rarely makes sense.

Thanks for putting it in really good perspective...I never really thought of it that way....heres my math..but buying the car isn't really worth it..unless I can have my dad's company to start making biodiesel

Cadillac (guessing) 20mpg highway / 0.050 gallons per mile
Jetta: 45mpg city / 0.022 gallons per mile
Cost per mile @ $1.92/gal:
cost per mile @ 1.73
Cadillac: $0.096
VW: $0.038
Dfference: 5.80 cents/mile
$5000 / $0.0580 = 86206 miles
If you pay $5000 for the VW it'll take 86k miles (2.38 years if you drive 36k mi/yr) to pay for itself with the difference in gas costs. Of course if you sell the Caddy that'll help, but buying a new car to save on gas rarely makes sense.
