I remember cruising round the Brisbane wholesale yards in 1990 and spotting an 88 model Mitsubishi Colt. It was the later 5 speed version, not the twin stick model. It was only 2 years old, very clean, had NT plates on it and was ridiculously cheap. I looked over it, very tidy, 95,000kms, high for 2 years old, but not too bad, why so cheap?

Asked a salesman, "because of the kms" was the reply. Went back and looked at the odometer again, 950,000kms.

Checked the log books and it had like a company log book in it and it had been serviced every single week for the previous 2 years. According to the salesman it was a courier car and was running from Darwin to Alice Springs and back every week Mon/Tues, Weds/Thurs and Fri/Sat.
There were no gaps in the log book so it would be safe to assume it had suffered no major mechanical issues during all those kms.
He reckoned it drove like new, but I walked away, too many kms for this black duck.
