Welcome! I'm new here as well, and have had my 05 Roadster about three weeks. It's been secured waiting for clearer weather (winters are so bad here in Mississippi) and completed paperwork. I find myself standing in the garage looking and smiling.

As has been mentioned, this is a great group. Many do some or much of their own maintenance, and maybe more extensive work. You'll find links to the service manuals, parts manual, and other information. You mentioned AMX's, so I suspect you may turn an occasional wrench.

Be sure to spend some time in the Roadster section.

Expect to pay 3X for normal parts if you aren't careful. AutohausAZ has correct filters and such at a fraction of what Chrysler will charge.

Enjoy!
