I think you are asking several questions at once. Let me parse it my way, and then you can get opinions from folks to argue one way or another for each.
#1 The routed track will ultimately be what you want. I don't know why, but everybody goes through the same phases... plastic track with heavy magnetic attraction (Scalextric, SCX, etc) then plastic track with low magnetic attraction, then routed track with no attraction at all, which more closely imitates real life racing. And it seems like that is where we all wind up, with the exception of established plastic track outfits that are not in position to change their setup.
#2 135 feet is a big track. You're lucky to find it intact, and I say, go for it. Invest whatever you have to as you set it up. It will last long enough by far to pay you back. How many lanes? It matters.
#3 About the kids... I started when I was only 11 years old in 1962. No magnets. Kids are better at this than you ever imagined. Make yourself comfortable, and they will still beat you to the finish line from time to time. I have a 150 foot 8 lane Imperial (grandfather of the King track), and I have every reason to believe that whomever gets it from me someday will have kids going nuts on it, just like I did back in those days...
