Glad to hear from a few of you, thanks!!
I have put about 500 miles on her, and have not yet seen 60MPH so my lead foot. I have also spent quit a bit of time detailing with the AC on which may explain the low MPG. I am liking this car more each day. My neighbor who bought a new 5 series has it in the shop and oil stains all over his driveway. My 7 year old SC appears flawless. I found the answers to all my questions, and everything with the car has been very straight forward.
I know it has the same drivetrain as my LS but the two cars share nothing. The LS is a great family car, and has a lot more features, that may be in later year SCs. Our LS does not require the key in the ignition, has a frige, massage seats, a six speed tranny, and may be a little quicker. If given the choice I rather drive the SC. I love the top down, it gets a lot more attention, and is not so stuffy.
The interesting thing is the 06LS was the record holder for the most reliable car you could buy. All models, all makes, any price. Now that the 07LS has been redone, the SC holds that distinction. A convertable sports car is the most reliable car you can buy. Wow!!
The ML stereo is disapointing, and I really miss pluging in my Iphone. I bought the car in auction, and was cross shopping a 911. Very glad I went with the SC, almost as comfortable as my LS (I dont have run flats)
The kids love riding in the back, and they call my car the transformer. My daughter is not too happy though because I traded our 07 RAV4 in to buy the Lexus, the RAV had dual 11" screens in the back and a playstation.
All in all, very happy. If I can drive it without putting a fortune into repairs, and it looks like I can, I may keep this one till the wheels fall off.
