That's not a bad deal. Mine is an 04, I bought it with 54K miles for 13,500. Brought it up to 15K with gap coverage and extended warranty. As far as Mopar mods goes, they are great if you want just a plug and play setup. No tuning what so ever! However like chad mentioned, you can make more power with aftermarket parts.

PM me with any questions you may have SRT4's and I'll be more than happy to help you out
