Technically any car can drive any distance... all depends on how much you're willing to spend ;) This topic invariably shows up on every car model's dedicated forum. Now, original drivetrain? That's a different story.
not really, i have two good friends that both have 1990 ls 400's one has over a million miles the other over 700000 miles, both have original motor and transmission, only add on's on the motor replaced air compressor, alt, water oump the body looks rough after going through two family members but both have had oil changes every 3000 miles timming belt changes ect. the guy that has the million mile car bought a new one at 250000 miles and gave the 1990 to his son in law, after a month he traded with him and took the 1990 back and said it was a better car.i really believe the 1990 was the best ever built,
