I just purchased a used 09 wrx with 43000 miles. The car seems fine, but how do I know it's not ragged out? I'm ready to purchase mods but don't want to risk it. My mod list consist of Accessport, short shifter, Downpipe exhaust, TMIC, etc. Suggestions and any help would be awesome. Bought the car from dealership and it looks like the guy just used it for everyday driving. No mods on it and the carfax said it received it 40000 mile schedule maintenance.
