how to save money building your car

Guys buy,build,and do a lot of things to their cars, but it doesn't have to be expensive.
How can you, or have you saved a few bucks on your build?

Take 2, Make 1!

I was able to buy a rust free little old lady, 52,000 mile, 69 dart (2 owners, but just one family) with a badly smoking slant 6/auto, 9" drum brakes, and a 7 1/4 rear end; the only factory option, power steering, even had the heater delete, for $2400 & $1600 in back fees (they never turned in the plates, just parked it and forgot it for 6 years). 6 months later I found a rust bucket 74 Scamp that a young Marine tried built into a "rat rod" for his tour in Hawaii with a 318/auto, mild cam, new Edelbrock intake & Carter AFB, disc brakes, 8 3/4 rear end, Rally rims w/new tires, flowmasters, heavy duty shocks, a new interior, etc, etc.... Then when he left the island, he just gave it to the base Auto Hobby Shop to auction off instead of shipping it back to the mainland (did I mention the rust, the left rear fender collapsed when I tried to prop the trunk open). While waiting to be auctioned, someone busted the windshield. No one else seemed to look past the cosmetics so I was able to buy it for a mere $250 (the minimum bid). So after a year or so of work and about $600 more in new parts she may still look like a little old lady, and may not be a "real" hot rod, but underneath that "Lil' Scamp" makes a great little cruiser that's only cost about 5 big ones.
