General questions from prospective future SVX owner

I'm looking for a car to replace my son's 1999 Daewoo Leganza, which was a nice-looking car (styled by Guigaro, but basically a 3/4 scale version of his early 1990s Kensington Jaguar concept)with lots of amenities, but a wretched GM engine.

The SVX seems like it might have the right balance of initial cost, reliability, and style. I've always liked Subarus, although I have never owned one. Also, in light of the Daewoo's destroyed valvetrain, I like the fact that a broken timing belt won't grenade the H6's valves and cams.

I have some questions that aren't in the FAQ, though. Some of them are mine, some of them are his. I think it will be pretty easy to tell which are which

1) He'll be taking it to law school next year. Can anyone point me to good SVX specialists in Atlanta, Washington, and Boston? He'll change his own oil, but otherwise modern cars are pretty complex...

2) From the FAQ I understand that front brakes and transmission cooling are issues. There is much mentioned about the transmssion, but what about the brakes? Are there stouter rotors that are drop-in replacements?

3) What's the parts situation for the 3.3L H6? Is the Outback's 3.5L a development of this engine (meaning parts will be around for a while) or an entirely different design? (For that matter, in case of failure, is the Outback's engine a drop-in replacement?)

4) He'll want to install some audio equipment in it. Audio questions:
-How deep are the front speaker holes (6.5" diameter according to Crutchfield, is that right?), and are the door speakers in sealed enclosures or infinite-baffles?
-Are the rear-speakers enclosed or mounted in free air?
-How difficult would it be to enlarge the rear speaker holes to 12" diameter.

The other cars I'm considering for him, for what it's worth, are a mid-1990s Volvo 940/960, mid-1990s Infinti Q45, or a square-headlight Mercedes 190E/300E. But if I can get him something as interesting as an SVX for the same or even less money....

Thanks in advance,
