How about the fact I have 9 340 core engines in my personal collection at the moment, a few of which I bought so long ago that they only cost 2-3 hundred complete?
if you have the 340 already, then it's a no-brainer vs 318. But if a guy (or gal) had to buy TODAY, what would move his A-body faster for a 3k budget??? Is the 318 the better choice in this situation?
