lower the rate;
c) that to take advantage of such a reduced rate, a customer must
purchase additional options or services;

price of the vehicle or options or services purchased;
e) that the offer expires after a limited time period; and
f) any other conditions, qualifications or limitations which
materially affect the availability of such rate.
