WHen I was in HS I was already as car obsessive as I am now - but also even more dumb. I convinced my New Braunfels friend to go in to San Antonio to look at a car I found in the paper auto trader magazines we had to rely on in the late 80's - the car was an MG with a 427 somehow stuffed under the hood. As we got to the address we realized it was a very unsafe looking area of town, and we were somewhat dumb for even going to look at this, so we turned my buddy's Chrysler Cordoba around (takes 50') and headed home.
The other car I took him to look at was right in New Braunfels. It was some 1970's era football field long convertible - but the owner had chopped out the chunk of the car from behind the front seats to the trunk and moved everything forward. So big overhangs and short wheelbase. So these two 17 year olds show up and the owner tosses us the keys and lets us take it for a drive without even accompanying us. We were gone a long time and drive included us "jumping" some railroad track crossing - at least when we came down off the high point it sounded like we wrecked the underside of the car, to the point we stopped and looked everything over. Then got back after the long drive and gave keys back and said "nah".
