1999 Porsche 911 Carrera safety

[jackson_g]

Hi,
How safe are these cars? I have found two used 1999 Porsche 911 Carreras that are both selling for around 19-20k and have 60-70k miles on them. I am a pretty new and young driver who currently drives an Acura MDX and am looking to buy one of these two cars (of course after I get a mechanic to certify that they are in good condition), but the car's safety is paramount for my parents to consent to help me pay (and extremely important to me as well). I couldn't find crash test results, though. FYI I consider myself a pretty safe driver, I never speed (at least not more than 5 mph), never change lanes without signaling, run red lights, drive impaired, etc. but I know that accidents happen even to safe drivers, such as a rear-end, a T-bone, or even a head-on. Basically I want to know are these cars safe? Would you let your teenager drive one? I was also considering a 2002 Corvette, so would you say 911 or Corvette is safer? I know that the Porsche has a rear-mounted engine; is that an issue? Thanks.

(If you can provide some kind of chart or a link to one, that would be great. I'm particularly interested in knowing about the Porsche's rollover safety and performance when hit from the front, side, or back, but all information is preferred and welcomed.)
