Anyone have a good dealer experience in the niagara falls/ buffalo area of USA for warranty work done on their Ontario s2k bought used from the USA. I purchased my 2007 s2000 in march/2011 here in Ontario and am now (sept/2011) experiencing some engine noise that my local Honda dealer can't explain without tearing apart the vslve train and perhaps further to find the cause (quotes start at 400$ to start, no idea how much to find problem dealer says). Car still has a US warranty on it, Honda USA says any dealer should be able top fix it, just would appreciate a referral if possible.
