My boyfriend and I are going to be taking his car (2006 Chevy Cobalt LS 5 speed manual transmission, about 13,000 miles) on a road trip next month. The car runs fine, and he gets regular oil changes. Just wondering if there's any special service we should think about getting before we head from CT down to TN? Change the spark plugs, or wires, or anything else like that?? Any help would be appreciated!!!
