REDWOOD CITY, Calif. -

Although wholesale prices for three of the four vehicle segments OPENLANE tracks slid down in June, the Canadian Market Index still ticked higher.

OPENLANE said its June Canadian Index settled at 98, which was 1 percentage point higher than May and 5 percentage points higher than the same month a year ago.

Meanwhile, OPENLANE watched prices for minivans, SUVs and trucks all sink versus May.

Analysts determined truck prices softened 3 percentage points, while SUV prices dipped 4 percentage points. Minivan prices dropped the most — 7 percentage points from May.
