I am surprised. Are you saying that you got exchange bonus for selling a Maruti and buying a Hyundai? Meaning Hyundai will give exchange bonus if I sell any car and buy a Hyundai? That sounds great.
AFAIK, exchange bonus is usually applicable for cars of any make. You may be referring to the loyalty bonus.
Althoguh for me, the positive surprise was that Hyundai was not actually buying my car to give the exchange bonus unlike other companies.
I got the following for my Fiat Linea on 8 Oct 2009 from Concorde Motors, Dairy Circle, Bangalore:
Corporate Disccount: Rs 8 k
Cash Discount: Rs 6 k
Insurance: I got it done outside after availing of 50% NCB
Freebies: floor mats, mud flaps, car cover, idol, perfume, a box of chocolates & fuel coupon for 5 litres of petrol. Plus I was not charged Rs 5 k extra applicable for premium colour FTA.
