i recently planned to get a car and my loan was approved from RHB, However, now i wish to switch the car dealer and the new dealer said I can get my approved loan to be transferred over since I did not sign anything yet. The new dealer is in the process to do so, but somehow the previous car dealer got to know. Both are perodua dealers by the way. Now the old dealer is kind harassing us by calling off and on to tell us they'll match whatever offer given by the new dealer but would not allow the loan to be transferred.

Can the car dealer do so since the loan approval is by right subjected to the bank's approval?

Yups better offer. Actually I did try to nego with the intial dealer but the SA had the guts to tell me the other dealer is just offering loads of freebies and additional discount of 1K to attract me...I was like - aren't I a customer and isn't it your job to indeed attract a customer So i chose to just go to the other dealer. But now the prev SA keeps calling to say they'll match the offer, though i seriously am not interested to go back to them.

I just want to have my loan which is already approved by rhb to be transferred to the other dealer...

ok noted, thank you! have informed the new SA to just proceed with other banks
