Thanks Ecky. I got the chance to test drive one a few weeks ago and it was pretty much what you said: Not necessary, but overall driving enjoyment and ease is much increased with it! I liked it as it was very similar in feel to my Neon in terms of the driving experience (minus the power... my Neon has a lot more go, as expected of double the engine size!) but the clutch, transmission, steering, seating, etc. was all familiar.
I liked it enough that I'm going to go look at another one today and hopefully purchase. I'll be in the Portland area in a few weeks and have already contacted Bumblebee to see about doing a pickup/exchange onsite (Would be using my Neon, but have the old IMA pack with me). So I'm obviously sold on the idea.
