If you like that year and color combo, I don't think you can go wrong. You're definitely going to have a project on your hands though.
That ebay 'T4' may not have a long life span so keep that in mind. I don't particularly care for some of the work that has been done on the car; but, I'm not the one buying it either.
You can run it without a Maft-Pro. You'll need to buy an AFM and maybe a few other things. The parts would be much cheaper than buying a Maft-Pro w/Speed Density Harness. However, if you've got the cash and are going to end up going Maft-Pro anyway...just buy it now.
If you have access to a truck and car trailer, just trailer it home. Otherwise, drive it without the cat. You'll just break a few noise ordances on your way home!
In all seriousness...trailer it home and work on it there. You could get the stock AFM and other associated parts...you could even get the Maft-Pro...but then you'll have to go to his house and install all of it and "HOPE" that nothing else is wrong.
Know what I mean...
