I am in the process of purchasing a 2009 Challenger SRT8 Auto with 18k miles and wanted to get some recommendations on what to look out for. I inspected the car on a lift and did a quick test drive but could not find any obvious problems aside from missing front and rear floor mats and the tire kit for the trunk which I assume are easy to get. The 3/36 warranty runs out in less that 2 weeks so I will be bringing it to a Chrysler dealer for a diagnostic before finalizing the deal. The car didn't throw me back in my seat as much as I expected. My 06 300C 5.7 AWD seemed to have almost as much pep when it was new, but perhaps the adaptive computer settings have muted this 6.1 now that it has 18k on it like my 300C did after a while. Since the 392's are a bit quicker, I'd also like to hear about any performance mods that provide a good bang for the buck without sacrificing mechanical reliability. The cold air kits and tuners seem to be the most popular, not sure if I am missing anything else. Thanks for any info!
Check the rear wheel wells for rubber, if you find rubber melted to the wheel wells the car may have been raced or abused (think smokey burn outs). Also you should pull the #2 fuse and leave it out for a few minutes so the adaptives are reset back to stock so they can learn your driving habbits that should make the car feel more power full too
