Welcome, it would be a great upgrade to that old Cavi! Very fast, full of torque, handles great, stops great, total sleeper!
Problems?

What problems?
But seriously, there are a few glitches, no real major issues. Some have a leaky cam seal that makes the car act funny until it's replaced, and the ECU tuning is in a constant state of evolution, but nothing that Saturn isn't right on top of. Some people have had some bad service department issues, but those were mainly isolated, dealership specific issues.
DON'T read the sports compact magazine for your info on it though! Test drive one, and then read the mags, you'll cry BS on every point they make, even when trying to be nice to the car.
Last but not least, I live in Chicago, and have yet to see 1 other Redline. Ok, that's a lie, I did see a silver one parking at the autoshow, but that's it. IN 3 MONTHS!
