Sort of a strange question..... I've driven 13 hrs w only stops for gas.... gas mileage on a long trip is typically 28 mpg.....
so long as your car is in good mechanical condition, the sky is the limit.....
Thanks for your response. mine is a 2006 with 131K miles on it. my only concern is the timing belt has never been replaced - running smooth so far! Just want to be sure if its a good idea to hit the road trip with the old timing belt or replace it with a new timing belt.
If you put off replacing the timing belt and it fails, you'll be very unhappy with yourself.... One has to balance any benefit of waiting before replacing it against the risk of engine destruction and being stuck somewhere...

Your TB and WP way overdue. Don't risk to ruin your engine. WP failure makes TB break inturn destroys the engine.
I drove my 2008 from San Jose to Irvine (CA), about 400 miles non-stop. I wasn't sure what would run out first...my fuel or my own bladder capacity! It took about 6 hrs, driving 80 mph most of the way. What wasn't an issue was comfort. I've yet to experience any butt or back pain while road tripping my SC!
I haven't done my TB yet either, with 65K on the odometer. I wouldn't bother inspecting the belt. I've yet to see a bad looking Toyota/Lexus belt in all my years of wrenching. As G-man says, the most likely point of failure is your water pump. If it ceases, you will break the belt unless you get the engine shut down immediately. But, at least you will get a warning with noise and high engine temperatures (hopefully with a high-temp warning light).
If you have changed your coolant according to schedule, your water pump is likely fine. The additives in the Toyota coolant keep the pump bearings lubricated. On the other hand, if you haven't kept up the cooling system maintenance with Toyota pink coolant, you should start thinking about scheduling the TB/WP job.
Thanks for your response! except the TB(previous owner doesn't remember if its been replaced), rest everything has been taken care of. OK, will do that! Cheers!

80 mph gets 28 miles/gallon ??
Yes, the trip computer said 29 mpg, but 28 is probably more accurate.
Was your coolant drained and filled with fresh pink Toyota coolant every 3-5 years?
My longest trip in the 2006 SC 430 has been around 250 miles or around 3 and half hours. My MPG was about 28 if I remember right. Had no issues. Now as far as comfort that is another issue. While the SC is not bad it is a far cry from my normal road trip choice, which is my 2010 LS 460L. The LS is what comfort is all about.

SC430: What's the farthest/longest you have driven without any breaks/stops?
