What is the most mileage on a one owner car you have seen? I have 800,000 on my ‘96 Acura Integra. I do all my own maintenance. I rebuilt the engine at 477,000 due to an oil pump oil leak. The original automatic transmission has never been touched other than annual transmission fluid flushes which is about every 35,000 miles. All the critical components have lasted well over 500,000 miles before needing repair- alternator went out at 535,000. Ignition coil went out at 630,000. Igniter died at 670,000. Fuel pump died at 680,000. Struts last around 350,000. Wheel bearings last 200,000-600,000. I still drive this car every day.
The highest mileage vehicle that I've seen is a '93 Chevy Silverado 1500 5.7 with 750k miles with the original engine and original transmission.
That is quite some mileage on that Acura. Did you rebuild the engine yourself?
Yes
