I bought a Honda Jazz about 18 months ago.
In terms of discounts/promotions, Beer Monkey, they throw in various goodies free, but they didn't discount the purchase price (-Tinted glass, Alarm system, carpet mats, chrome exhaust tail pipe! etc).
I put down about 35% deposit and am repaying over 3 years, that got me a lower interest rate of 2.70%. Repayments about 11.7K per month. It was through National Finance, who have since become a bank - Thanachart, sounds like same as Ray. They also do the insurance.
I note they now have a nice new branch on the Khon Kaen road, (Tahan road), in addition to the older small one on Phosi road. And they do seem to have exclusive rights on pretty young girl cashiers.

Needless to say, I always pay early!
