The electronics are generally more affected by age and duty cycles than mileage. Low mile cars have their own set of problems from excessive time sitting without running and frequent starting and stopping without warming up. Given the age of these cars a 50k mile car is probably in the sweet spot of drivability and mileage.
On the other hand if your into low mile cars for their (theoretical) value retention or NCRS appeal, you probably already know what your looking for.
Good luck with your search.

OP:
Yep! Hans is right! You cannot compare anything you know about SBCs to the LT5. I've been rebuilding and hotrodding SBCs going back to the late 60s. But, these LT5 motors all were hand assembled and tested. With a 12Qt oil pan and regular changes (basic maintenance), these motors are just getting broken in at the 100k point! In fact, I saw a car sent to Marc Haibeck for "freshening up" that had 170k miles and was used as a track car. It had some wear, but it was still w/in factory tolerances throughout! Try THAT with just about any motor you can name!
Point is, I wouldn't give a 57k motor a second thought, long as it was maintained (of course).
