2006 Cadillac CTS

Selling Cadillac cts 2006 with 164446 millage on. It's being a great vehicle since I bought it but as an almost 20 years old car has its issues. The engine light is on, not sure what's the reason for the engine light to be on. It could be an eassy fix or it can be something difficult to fix. Even though the car is drivable, I use it as my daily car. Other issues that it has its that the back bumper is cracked and the dashboard is cracked also due to the sun and the time. One last thing is that the exhaust is not connected to the catalyst so it sounds loud. You can come and do a test drive and if you have any questions you can DM me
