Hi all, first post here. I am looking to replace a 04 Spectra with possibly a 2006-2008 Colbalt or G5. Firstly, I can get a 2008 G5 with around 52K auto with most options for around $9500 taxes in, or I could get a 06 2 door Colbalt standard fully loaded with 80K for $7000 taxes in. What are some things to know about these models based on the kms? Do timing belts have to be replaced on these models like my Kia? What are the common things to be aware of? Thanks in advance.
