Thought about it a coupled of times. The thought of running EP in regionals is not enticing (fields too small) and to convert mine or build a decent EP car to run nationals is cost prohibitive right now for me. We have large ITA fields in Cendiv, and so the racing is always good even if most of the fast RX7's are racing for the last trophy position in ITA. I've seen a few national EP RX7's for sale that are generally in the $15k - $20k range.
