Acura East in Ajax is ok. I found them to be courteous and on time in terms of service. I got a good deal on my last car, an 04 TL, that I now have traded for a BMW. I have been on several Acura forums for the last five or six years and the one dealership that seems to be highly regarded is the newer one in Markham. If your friend would like to read some good threads on the RDX, go to
http://www.vtec.net and look at the "RDX" forum. There are a couple of quite knowledgeable guys on that forum, one of which is working on some aftermarket upgrades. Look for posts from "notyper".
