is the 2006 Cadillac CTS a Good Strong dependable car?

A 14 year old Caddy? Probably not.

Nope! My next door neighbor had one she bought brand new. She had it just long enough to pay for it. Then she bought a 2012 model and traded that one in before it was paid for. Neverending check engine light problems, accessories that stopped working like the power windows and air conditioning, leaking sunroof, and so on! They're absolute junk!! Hope that helps! Jim

Mine has been running strong. I bought it in 2014 and I've only had normal wear and tear issues. When I bought it in 2015 or 2016, it had 98k miles on it. Now I have 152k and I've had it tuned up once. I just had my transmission flushed about a 2wks ago because the light for change transmission fluid came on. Other than that, anything else I've replaced, I realized it was TIME to replace them. But since it's paid for and I don't want a car note, spending the money to repair once is better than a 70 month bill. That's just my opinion. AND mine still looks new except they are making them more rounded now.
