how to obtain a manual for 4dr sdn ls

Hello You can find these at ebay. Just click here: http://search.ebay.com/search/search.dll?from=R40&satitle=2005+aveo+manual CarGrrl

you can find tham on ebay or other numerous car dealers on the internet but i would just go to the closest cheverolet dealer and you could easily pick one up there

Go to the parts store or Search for "haynes" aveo manual on amazon or google.

Hold on... Do you mean the repair manual or the owner's manual. For repair- see above. For owners- search "Aveo Owners Manual" on ebay or stop into a GM dealership and have them order one for you.
