2003 Cadillac CTS repair cost alot higher than on other car

Would love to have you as a Cadillac owner, as well. As far as being more expensive than other makes(specified Buick), there should be comparibly little difference in the basis. In terms, labor rate at a luxury dealer may run slightly higher than a more standard line. The parts would be about the same, as the manufacturer sets a retail price that is non-discriminatory. There can be different technology involved in the higher line that may translate to higher cost, but every line is experiencing that in one way or another. Insurance may be higher as well. Be aware that you are showing interest in a car that is already 6 years old, and is the first year of the model run.
