I have to choose between two Ford Rangers: 2001 4.0L XLT SuperCap w/ 7,000 miles or a 2003 3.0L XLT S/C w/ 30,000 miles.These 2 Rangers are priced between $500.00 of each other. I will use this truck for my contract painting work. My 93' 3.0L Ranger worked fine for me. My concerns are the 4.0L gas mileage & it's relatiablity. Any suggestions?? Thank you.
