I'd go for the easy stuff first. Load test the battery and the starter at Advance or Autozone. I read a post on here recently about how easy the starter is to remove. I haven't had to do it yet.

My Park Avenue is up up there with about 250k miles and I don't see any reason it won't go 300+ before the rebuild. Hopefully you've got one the previous owners took reasonable care. There's a lot of good advice available here on the forums, and this might be a good opportunity to forgo the repair shop, build up a set of good old Harbor Freight tools, get a few scraped knuckles and some grease under the fingernails.

Good Luck!
