That is not correct
Lexus has routinely sold CPO with fender benders on carfax
Here is my personal ISF I owned and bought new. I was hit in 2009. It’s in carfax.
I dumped car in 2011, at which time lexus dealer did CPO
2008 Used Lexus IS F Lexus IS-F Sport Sedan at Europlus Motorsports Serving North Brunswick, NJ, IID 17111109
Additionally there is a huge thread on clubkexus now about 3 people who bought CPo to later find out accident cars. One is suing Lexus of Austin right now to get them to take the RX back
Per club lexus (there is verified chat with lexus representatives), they will CPO a car with 4 panels being repainted
We bought our IS250C as CPO last summer and that is what the dealer (Lexus of Towson MD) told us, that once it has an accident they won't do CPO. Maybe it's a dealer decision, but they led me to believe that it was Lexus Corporate with the rule. I have been over the car very carefully and I can find no evidence of paint work at all, no masking marks or overspray. All of the body panels have the factory VIN tattoos. I really only wanted CPO for this car due to the insanely complicated convertible roof mechanism.
