This is an amazing opportunity you got! Looking forward to hearing on what you learned and whether or not you felt they were giving you honest information or just misleading the crowd.

Completely agree with you @frostymulder on the fact that not all old cars are built like tanks. I guess I meant it more in the sense that the mechanics of older cars are generally simpler than todays cars
