Found a turbocharged RS...

I found a turbocharged 2.5RS near me, $15k with 47k miles. I gave him an e-mail and this is what he has said so far:
It has a stainless Borla header which has been modified to go into a custom 2.5" stainless up-pipe to a turbonetics t3/t4 turbocharger. Then there is a custom 3" stainless downpipe which goes back to a prodrive cat-back. It has a turbonetics delta-gate waste-gate, a greddy blow-off valve, and I believe its a spearco intercooler (not positive) but its top-mounted and uses air from the scoop like the wrx. It has a J&S knock retard system on it. The car only runs about 4 psi of boost right know, but its still quick and safe. The suspension is
Pro-drive springs, shocks/struts, and it handles really well

Normally, I'd go visit it in person, but the problem here is that it is just on the border of too far - 100 miles away.

So, I'd like to ask whether the information given shows reliability - whether this warrants a visit in person, despite being a long drive.

Thanks in advance.
