We live in Edmonton Alberta. Known for rock chips due to the boom and bust economy. We previously had a 1992 Lexus 400 that was an original car to Edmonton. We were the second owners, bought through a dealer as a local trade in. Absolutely no rust. Just sold it this year and bought a 2005 local 430 also a trade in through the dealer.I own an Acura TL local car, no rust. We have owned a number of vehicles, mostly American and Mercedes, now Japanese. Always happy with them. My concern is that Lexus may not stand behind their product. I think there is a flaw here and a serious one. I was just wondering if other owners have problems with rust forming near the strip running the bottom of their cars. I see on forums that the Lexus 350 has paint problems and just checking out if this is common. Lexus dealers did not have problems with our money. It was good. I do not expect to have problems with a premium car. If it is their problem I expect them to stand behind their product. They are not the only car people who got complacent with their products.If their quality is based upon a reputation that may be based in the past I would like to know for future consideration.
