Hi there --I just bought a Sonata in Nov of last year, and they only gave me a three year warranty on the powertrain. Now, I'm seeing commercials for "Canada's Best Warranty" and saying it's a lot more now, like seven!. I'm just wondering if anyone knows the address of the head office and who I could contact in a possibly fruitless quest to bump up my warranty to match what they're advertising, since I feel a bit gipped. Thanks, Jack
