Bought a Redline a few weeks ago for my second car having got an STiR in the other car and been very impressed with the STI-r performance. By all accounts the the Redline is the same platform as the 9500ci and STi-R and that was the performance I was expecting from the Redline. Unfortunately the Ka performance of my Redline is poor - not even close to the STi-R (when tested either alone or together) and certainly no better than my 3 year old dashmount STI or V1 on Ka.
I have to say I'm surprised/disappointed given all the reviews here and the stellar performance of my STI-r with which it supposedly shares then same platform. I am willing to accept some manufacturing variation but for $500, inferiorirty to older models will not cut it.
Needless to say it will be going back, and Escort's customer service when alerted to this issue has been neutral at best. Be warned.
