I don't know how much an ambulance is worth, but I can tell you that I have over $7,000 tied up into the drivetrain of the van I'm building. I'll have about $3000 into JUST the axles (dana 60 and 14-bolt), another $1000 for my tranny, $800 for my engine (tbi 350), $1700 worth of wheels/tires. That's almost $7k right there, so it doesn't sound like too bad of a deal to me, especially if it's what you want....
