Hello, My name is [XXX]. I bought my car from Longo Toyota in El Monte about 15 months ago. The car was certified preowned and had a Carfax report with no accident reported history. That is exactly why I bought the car, because this was going to be my family car. So I bought it and have been driving around my daughter, who just turned one for over a year. I also work as a Behavioral Therapist and drive around kids with autism in my car on a daily basis. It wasn’t until I decided to trade in my car that it was discovered that the Avalon car has frame damage, which was discovered by third-party. A car condition expert came to check out the car and discovered the frame damage by using a true frame meter and a paint meter. Now Longo Toyota in El Monte has gave me the go around and hasn't even checked for frame damage. Longo Toyota is asking me how much would I want for my car and asking me about my car's value. There is clear fraud going on, and the fact that this is the largest car dealership in the country makes me wonder how many more people are driving around in cars that have frame damage as well. Best regards, [XXX] “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Toyota Avalon verdict →
