I'm looking to purchase a 2003 LX470 at a local dealer for the wife to replace our 2009 Honda Pilot. I've checked the VIN on the Lexus website in combination with carfax and I cannot find any indication of whether the T-Belt has been replaced. Is there an indication such as a seal or similar under the hood that indicates whether replacement has been made? The truck is selling for $19,500 and has approx 135k. Looking forward to purchasing a 100 series
