Jsuit, the first 400 or so cars in the '05 run had a speedy sleeve installed in the crank for a leaky seal. No one has reported any problems with this fix. The early to mid '05s also have the cast A arms on the suspension. There was a $10K price increase that went into effect July '05. If a car was ordered before July '05, it was not affected. Most '05s have a screen in front of the radiator. Late '05s and all '06s do not have this screen, but a slightly altered front bumper. There are plenty of pictures on the Forum to documnet these changes. Other than a latch change here or there, the cars are pretty much identical. Silver was offered only in '05. Tungsten and Heritage Blue Livery were offerd only in '06. Standard calipers were black, red and grey being a $750 option. Standard radio without subwoofer was a Sanyo with Macintosh radio and sub as a $4000 option. Center stripe is a $5400 option becasue they are painted on. BBS six spoke wheels are standard, BBS forged wheels a $4000 option. Livery paint job was a $13K option. Yo0u cannot import an American version into Canada. Canadian versions have a different front bumper (heavier), a longer rear bumper, nad no Mac option. By far and away, the best color is RED.
