Getting guaranteed car sales data for Spain is difficult. From what I did find, the market back in the 60's was limited to brands made within the country. In 1961, less than 70,000 cars were sold so not a market big enough to support many manufacturing plants. Sales grew well and by 1969, perhaps 380,000 cars were sold.
Below are the sales as accurate I could get for 1969:
