Since bringing you the story of Irving Gordon and his three-million mile Volvo earlier this year, I've gone down the rabbit hole of mega mileage.
It seems Volvo and Mercedes dominate the top-ten list of mega-mileage motors, although oil company Mobil went with a 1990 BMW 325i as a test bed for their engine oil research thirty years ago.
At a quick glance, it looks like a lovely example with just 40,000 miles on the clocks from regular road use and great bodywork all round, with just one owner on the log book. That owner is oil company Mobil, who decided to use the six-cylinder BMW to break the million mile marker, without ever leaving the garage.
Mobil didn't totally deprive the car of love. They followed all BMW's recommended service and oil-change schedules. After 1,000,000 miles on the treadmill, the car's power plant was taken apart by mechanics, who were astonished to discover that engine wear was negligible and still within factory specifications for a new car. Both Mobil and BMW were over the moon with the performance of their respective products, the 325 now free of its shackles and touring car shows around Europe.
