Hi, I'm new to this forum and do not currently own a Redline but am looking for my next car and as of right now it is coming down to an SRT-4 or an Ion Redline and some of the things that the Redine has going for it is that it says on the Saturn website that it requires 87 octane gasoline and has much lower insurance prices. However, looking around the forums it seems that people are putting 91 octane gas in their redlines and was curious as to is that what the manual says it requires or is that just preference for a slight increase in performance? Also, if there is anyone else who lives in Jersey I would like to hear about the average insurance costs for the Redline (do they bracket in with the other ion quad coupes or do the insurance companies actually recognize the Redline as its own individual model? I ask because I went to Geico.com and after entering the VIN number for one it didn't have the model listed). So basically, does the Redline REQUIRE 91 octane gas or is that just driving preference and is the insurance relatively doable for this model of car, any informative posts I thank in advance.
