Hi All, Thank you for your advices and concern. I'll let you know the progress of the case. (actually there isn't much progress) After 7 days of posting this thread, which was 15 Feb, We (my friend who is the official owner of the car and me) firmly notified the dealer that we're not going to pay for the extra but we'll stick to the original contract. Since then we haven't heard anything from the dealer. I assume the dealer might have managed the problem within their dealership. Even if they go after a regal process, we've decided to stick to the original contract and play along with it. If that (regal process) happens, I'll let you guys know. Thanks.
