On paper the '06 is down on Horsepower from the '05, but that was due to a change in the way SAE calculates HP, so ignore that.
The '06 had a slightly revised nose, LED tail lights (instead of bulbs) and a six speed automatic (which displaced the '05's five speed).
The biggie IMHO, is the transmission. It's the "new" generation that is finding it's way into the rest of the Lexus line.
Buy the '06.
You will love this car and hate the tires (run flats)

I have this same problem with my 2002 SC 430. Had it back to the dealer 3 times, but they could not identify the problem. A nuisance item. Anyone else with this problem?

I also own a 2002, I have been through 4 sets of tires. I have over 115000 miles on the car. I recently bought the latest run flats by Bridgestone at the tirerack.com on line. These have made a substantial difference in the ride quality and the handling. I get around 25,000 miles per set of tires. There are many spare doughnut tires and mounting kits available from the dealer as well as on e-bay. They just take up too much room for my liking. I often carry a bicycle and golf clubs in the trunk and do not want to lose the storage space.

Golf clubs!!! a full set with bag?
Oh yeah, I took off the run flats and it was the best thing I could have done. I might need to call AAA for a tow if I get a flat but the improved ride is woth the risk. My dealer is storing the run flats (for free) in case I ever change my mind.

why did you have to replace your power steering pump???? I am actually having a noise issue with my 2002 SC430 & thought it may be related to the power steering pump but I have no steering problems. My engine sounds like an airplane when I accelerate and I hate it, what do you think that could be if you have any ideas.

The reason your engine sounds like an airplane is because what makes an airplane sound like it does is the propeller. Your radiator fan blades are like a propeller and when they are on all the time they will really roar. The fan clutch should disengage when the engine (and forward speed) rpm's increase as the cooling air is being provided by the forward movement of the car. The radiator fan is only there to provide cooling airflow when you are sitting still or moving too slowly for the normal source of cooling air (provided by forward motion) is insufficient to properly cool your radiator. Check the radiator fan clutch - I suspect it's locked up and never releases as it should. When your engine is cold (AND NOT RUNNING!!) you should be able to spin the radiator fan fairly easily only noticing a slight bit of resistance. If you can't spin it, or it is very hard to turn, it is locked up and will need replacement. This is not an unusual thing for a 5 year old car. It's also not a REAL expensive fix.
That's what it sounds like to me, but there could be other things causing your problem as well. This just seems to be the most likely, based on what I read in your post.
Good Luck on this,
