We can't give you legal advice, but having sold your used Mercedes Benz
as-is required the buyer to conduct a thorough inspection prior to the
purchase. On your end... You've completed your requirement as far as getting
a passing smog check. To answer your question directly, your MBZ could not
have the problems which the buyer is claiming and still pass a smog test;
this would be highly unlikely. Based on your smog test results it appears
your MBZ's engine was running very efficiently during the smog inspection.
