The M50 is among the best BMW engines ever made. Though not as iconic as the S14 and the S85, the M50 is a terrific engine. BMW offered the M50 on the selected E34s and E36s. A modified version of the M50 engine ended up in the sporty M3 E36. BMW engines of that era could go over 350,000 miles without any effort.

When Honda made its debut in the United States back in the late '50s and early '60s, domestic critics could not stop tearing the microscopic and grossly underpowered Japanese cars. Though more economical, American gearheads only wanted pure American-bred horsepower from a gas-guzzling machine. Things changed a lot in a little over 65 years.

Honda never claimed to make serious sports cars until recently. Though cars like the NSX were unattainable, the Accord and Civic Si would satisfy any entry-level gearhead. These engines can be modified to serious levels. When it comes to durability, Honda is well-known for its easy-to-maintain vehicles. A well-maintained Honda can reach 200,000 miles without breaking a sweat.
