1973 Mini Classic Mini

This 1973 Austin Mini 1000(Left-hand drive) has been converted to a fully electric vehicle. It offers the unique opportunity to drive a true classic that has been modernized.   With an all-electric drive train, this fun car offers the nostalgia of the classic Mini with the benefits of an electric car.  Currently, odometer shows ~7,500 KM (5,000 miles), which was reset as part of the electrical conversion process, so this represents “electric miles”.
