I am in the process of trying to decide which TRF car to purchase, a 416x or 417. I come to you with this question. Knowing what you know now, which car would you purchase, a slightly used TRF416x or a new TRF417? I have the opportunity to purchase a TRF416x with a bunch of spare parts for $140 less than a new TRF417 with a few spare parts. I have never raced on-road so I will have a learning curve with both cars. Would you go for the older car at a lesser price or a newer car with the newer technology?
