Proc print does not allow If or delete.

To show the records where a specific condition is needed use a WHERE clause:

WHERE Price_in_Thousands ne . ;

If you want to modify the data set you need to use a data step. 

data filtered;
set ashish.car_sales;
where not missing(price_in_thousands);
run;

If you want to filter the results to display in Proc print then use a where. 

Where not missing(price_in_thousands );
