Good question! I always do my own, but what am I going to do when I get a few more years on me and can't get down on the floor to do it myself?
First thought: I'll get my much younger son to do it for me while I watch and carefully instruct him about every step. (After all, he thinks the Cobra is part of his inheritance.)
Other than that: I think I would take it to a full service garage I'm familiar and comfortable with and bring my own
oil and filter.
If you are not doing the
oil changes, you better find a garage you can trust for everything else, so when you do, use them for the
oil changes. In fact, that might be a good, low risk way to begin developing a relationship; get them to do the oil changes and watch them. Make sure they are doing a quality job.
