Answer 1

your '))' were missing at the end of 8th line, and you had an extra ',' at the end before ).

This is fixed version

        CREATE TABLE car (
cid         CHAR(8)                     PRIMARY KEY,
reg_no      VARCHAR(9)                  NOT NULL,
colour      VARCHAR(15)                 NOT NULL,
maker       VARCHAR(20)                 NOT NULL,
model       VARCHAR(20)                 NOT NULL,
fuel_type   CHAR(6) CHECK((fuel_type IN ('petrol', 'diesel'))), 
eng_size    DECIMAL(20,15)              NOT NULL,
owner       CHAR(6)                     NOT NULL,

FOREIGN KEY (owner) REFERENCES client (client_no)
                ON DELETE CASCADE   
                                ON UPDATE CASCADE 
);

Answer 2

The line before eng_size field declaration missing closing parenthesis )

Change it from

fuel_type   CHAR(6) CHECK((fuel_type IN ('petrol', 'diesel'),

To

fuel_type   CHAR(6) CHECK(fuel_type IN ('petrol', 'diesel')),

Also, remove the , from the last line

FOREIGN KEY (owner) REFERENCES client (client_no)
                ON DELETE CASCADE ON UPDATE CASCADE
