You have kind of a difficult request. The US is huge and you won't be able to cover much in a week, your best chance for warm weather in from late March to early April would be across the southern tier of states from Florida to California, the car meet season doesn't really get going until summer and there's really no central location to target for interest in early Chryslers that meets your needs. That having been said, I can offer the following advice. The Walter P. Chrysler museum is great and probably would be in your interest, but it's located in Auburn Hills, Michigan (suburban Detroit) and most likely it won't be that warm there yet. On the positive side of things, Michigan and Northern Indiana have a lot of car museums and you can't beat going there to see old cars and auto history in general. There's the Henry Ford Museum in Dearborn, the Ransom Olds museum in Lansing, the Alfred Sloan Buick Museum in Flint, The Studebaker National Museum in South Bend, IN, the Auburn/Cord/Dues. Museum in Auburn, IN, the Gilmore Car Museum in Hickory Corners, MI and probably others I'm forgetting. Check out their web cites. I can't think of any places around there to look for Chrysler parts though. When I think of areas for Chrysler parts, Massachusetts comes to mind with Roberts and Andy Bernbaum parts and Atlas Auto Parts in Los Alamitos, California. Speaking of California, Southern California would be warm and there are some good auto museums there. There's the Nethercutt Collection and San Sylmar in Sylmar, the Peterson Museum in Los Angeles, the San Diego Car Museum, etc. Their web cites might help too. Finally, check out the WPC Club web cite for add'l info. They have a good National Car Meet, but it's in July in Omaha, Nebraska this year. Hope this is a start and good luck. John
