I purchased an 02 SVT with reworked frame damage from a front end collision that you could easily see by looking under the hood. The repair looked legit and it drove great. For reference he was asking $4,800 and it had about 75-80k miles on it. It had the cold weather package with heated seats and moonroof but it was not EAP. I got it for $4500, and this was back in 2008. The front fascia was from a regular ZX3 so I guess that might drop the price slightly. So based on that, I would say $5,800 is a bit much.
Definitely check out the carfax but don't rely on it fully as GreenEnvy said and have a mechanically enclined friend check it out with you if you don't feel comfortable assesing it yourself. My SVT treated me well and my current car is a salvage and has been great to me, you just need to know what to look for. Good luck man!
Edit: Oh and check out why that damn front tire is flat...
