I have 146,000 miles on a 1996 Z3, all original, never did anything to the motor except oil changes and tune-up. Still runs great
A maintained 4 cylinder M42 engine should last well over 200,000 miles.
A maintained 6 cylinder M52TU/M54 engine should last well over 300,000 miles, and it's reasonable to expect many to see over 500,000 miles -- long past the expected life of the body.
The high performance S52 engine used in the "M" version has production-date-specific issues, has higher maintainence requirements, and will typically see harsher use. It may have significantly shorter life than the other Z3 engines.

A properly maintained, stock Mazda Miata engine will easily last 200,000 miles on an engine and yield 25-30 mpg.
I have an 03' powerstroke 7.3 with 560,000 original miles on the engine and tranny, and she is still going strong.
I had a honda civic for 8 years and the odometer was 321785 km

My 1995 Avalon has 302,000 miles on it. Original water pump, plugs relaced only once. Original muffler. No problems, starts up every time.
I got 70,000 miles before my camshaft broke and I needed to replace the engine! This despite the fact that I never missed a scheduled service or oil change.
