The sales person had broke their 3 of the following promises.
1) The front bumper cover was missing. They had offered to fix it, but it has been over one month and they still haven't given me a bumper cover.
2) The car has lot of small scratches, but they said after buffing and polishing most of them will go away. However, after one wash 90% of them came back.
3) They offer 1.9% APR for 5 years, but last minute they changed it to 2.5% APR and my credit score is rated very good.
I called them multiple times to fix my problems but they have not addressed them, so stay away from Lexus of Englewood.
