$1950 plus repairs can add up in a hurry. I just do not see the value in this particular Firebird with all the known
issues. As far as the Mustang 40th anniversary, that would be a 2004 car, not 1994. Maybe just a typo. Need a lot more info before making a judgement call on that one, plus you are talking about a Mustang on a LS1 site
If I may make an assumption, it appears that you and your teenager could use some assistance in looking at cars and all the pitfalls attached with them. This should be a pleasant life-long experience (or memory) picking out a car together. Don't let a bad purchase ruin this. There must be someone you know that can assist. If not, and you are considering a Camaro or Firebird (probably any GM product), then posters here will assist. Your price range makes it difficult to buy a decent car but they are out there. You may have to travel a bit but it is well worth it. Just to give you an example, I was watching a 1995 Ford Taurus SHO ( a nice performance sedan) on ebay this past week for a collector car neighbor. It was was in excellent condition with a mere 27,000 low miles. It needed nothing! It sold for $6,200. That will be a wonderful car for the buyer for years and years most likely. Would it be worth spending a weekend to get a car like this? I certainly think so. Sometimes that is what it takes. My last two car purchases were days away, in Philly and in MD respectively. Not exactly in my neighborhood in western NC but worth it in every respect. Again, best of luck!
