I'd probably get it. But I'd ask to speak to the original owner first. I'd balk at the fact that the intake doesn't have the SVT logo. Use it to knock them down in price.
Also run the VIN to make sure it is a SVT. Too many of the little details makes it look like a SVT to me. But that intake bothers me, this might have been a blown motor that has been replaced. In which case that's even worse because then I'd be strongly worried that you don't have a SVT motor. Did you drive the 98 se? Was there a BIG difference in power?? If not I'd say stay away.
But if your answer is yes to the difference in power then someone just screwed up somehow and it will make one hell of a fun car to own.
