I found a awsome 2006 Lexus GX at a reputable Chrysler dealer...but everone tells me to be careful about buying preowned american vehicles up here in Canada. I just wanted everyones advice on this one. The vehicle was 11month Lease in California. The car fax says everything is ok...just no info on the Warranty (on the CarFax). The Saleslady says it has a full warranty. Should I buy this or keep looking??
