What does uncle hammers car symbolize to him and to the Logan family? What might his car symbolize to the bigoted whit citizens in the community where the Logan's live?

The car would symbolize social mobility of blacks to Uncle Hammer and the family. It would represent a visible shift in both economics and social status for blacks in the South. Whites would see it as offensive. They would be reminded of the South's failure in the Civil War. They would be angry and vengeful.
