    Cadillac CTS First Generation Forum - 2003 - 2007
    I found a really good deal on a 06 STS that a tree fell on. 300$ is all the guy wants . I have an 03 CTS and was wondering if any good parts were compatible. I have looked and seen the wheels are but how about the transmission and motor would be my main question. Thank you in adavance
