US sales for April surprised a lot of industry watchers this week as volume and SAAR came in below analysts' expectations. Volume dipped again in April, down 2.3% year on year to about 1.33m cars and light trucks. After four months, deliveries were 3% behind the January-April period in 2018. The seasonally adjusted annualised rate (SAAR) slumped to 16.41m units and both total volume and SAAR were well below the predictions.
