2006 Cadillac CTS: Sport Package

2006 Cadillac CTS 4dr Sdn 3.6L

I love the way this car handles and drives. I have spent thousands on big maintenance problems though. I believe it's because the car was only 3 years out from the first production year and therefore the tweaks had not been ironed out yet. The interior has held up very well. I love the soft cloth headliner that goes down to the dash. The rear leather seats have maintained their condition well. The design of the inside door panels mimics the design of the outside of the car. I love that the overall design of the car hasn't gone out of style. People still think that it is brand new after 13 years!

My Cadillac CTS is a definite reliable car.

2006 Cadillac CTS 4dr Sdn 3.6L

One of the main things band problems that I have with my Cadillac is such expensive maintenance on it. Just a simple oil change in cost me almost $80 band another thing to keep in mind when purchasing a Cadillac CTS is to make sure you always have a strong battery because with it being digital it tends to not want to work with a battery that is not strong so I highly recommend keeping that in mind. But this is a really good car and it's very reliable for the most part I have no complaints about it besides the maintenance upkeep this is a perfect car choice.

The screen will go in and out from occasionally

2006 Cadillac CTS 4dr Sdn 3.6L

I have no problems I absolutely love this car, good on gas, if you keep up maintenance there will be absolutely no problem, it drives great and when you start the car it's like a rocket taking off. I love the interior, when the car needs maintenance I take it to the Cadillac collision center and they get my car to good standing from maintenance to a great car wash highly recommend this car to anyone! Love this way it drives

Cadillac CTS pros and cons

2006 Cadillac CTS 4dr Sdn 3.6L

I loved owning a Cadillac. Such a nice, reliable car. Maintenance may get pricey due to the fact that they make it so where you almost always have to take it to a Cadillac dealer to get fixed but other than that NO COMPLAINTS! Gas also could get pricey and the car does run down on gas faster

Great vehicle, spacious and fun to drive

2006 Cadillac CTS 4dr Sdn 3.6L

This car has had it's problems but are easy fixes. The timing chain was replaced, the wiring in the headliner was replaced shortly after I bought it because of a short, currently the ECM is going out of it and it's putting the vehicle into a anti-theft safe mode
