As the other's stated, save & buy a beater would be your best bet. My 05 Dodge Hemi transfer case decided to let go 3 years ago on the Interstate, taking out the complete drive line from front to rear. With 285,000 miles on it, still ran as good as the day i bought it with regular maintenance until that dreaded evening. Trying to find all the part's to replace was more expensive than i was willing to spend, so "as is" & found a 95 F150 with 1117,000 miles on it for $2400.00, decided i'd drive it for a year, 3 years later i'm still driving it & have less than $1000 in repairs, not bad for a 22 year old vehicle.
My wife asked the other day when i was going to buy another truck, told her this one wasn't costing us nothing, may just drive it for a few more years or until the right 97 F250 Powerstroke (dream truck) shows up in m life.
There are good beaters out there if you take the time to look, it took me 3 months to find the 95, taking turns driving wifes or kids vehicles til then.
