I have the Spoon S2k. Though it's not as fast it's about as powerful as the normal maxed, and it's lighter. Meaning that Accel, Turning, Breaking, and Overall speed are better.
The Copperhead Concept Car is good, just a bit loose in stock form, if you have the Concept Car LM it's basicly the same in it's racing gear, cept it's yellow and purple. Actually the LM is better, but if your a Dodge fan and want to have the Copperhead in it's origional form, you'll like it. A bit of tweaking and it'll be fine anyway.
I'm working on I-C right now, like I said in the other thread. Can anyone give me hints on how to beat the blind corner test, I'm like .100 away from beating it and I'm pissed off.
