The guy we were building it for just sold his phone company a couple years ago. I went to his shop where he had two former Formula 1 cars in the front part that he does "vintage" racing with. In the back of his shop he had about 30 different vintage racing cars and motorcycles as well as several big rig transporters. He let us take a spin in his new Mercedes S600 - yeah, he has plenty of dough. And yes you can buy used engines, this one was about $250,000 before the rebuild. The bare block runs about $80k. Add $8000 for new rods, $5000 for valves, $1500 for pistons, etc...
