I have a 2003 Lexus with 140,000 miles on it is it time to traded in ? I had to choose between 2011 or 2012 LS 460 is there any difference or are they basically the same ?

Yes, they are near identical. The 2011 and 2012 are both 4.6L V8 380HP with some very minor insignificant changes in the '12 Navigation system -updated -- Rear wheel drive and I wish I could afford one - I would buy a '12

Thanks guys/ladies for the information. I am trying to keep my mileage under 150K before I sell it. Absolutely nothing wrong as it runs fantastically, but I am a Realtor and put on a bundle of miles on a car. I am hoping to sell the 03 for about $10,900...realistic? Buying a 2011-12 with under 30-39,000 miles realistic? Between $30-$33,000? Realistic

No .Not realistic. An '03 Lexus LS 430 in 'VERY GOOD condition retails for $7785, and most are in "Good Condition" that puts it at $7200 with 138,000 miles. A 2012 Lexus LS LS 460 AWD according to KBB in 'Good condition" with 35,000 miles retails for $33,730 Now you are in the ballpark. But just don't expect to get $10,900 for the '03 especially on a trade-in. That will be even less

Look up the retail/wholesale price on vmr international. I find this site allows you to filter down to the very close proximity of trade-in and retail according to the mileage. The site is very conservative in pricing strategy. It will help you. Up to 2012 all Dash and controls are very user friendly. Then came 2013, it became less intiitive. The dash is totally revamped. The skin and the interior are a complete redesign. Mechanically, 2013 is the same as 2012 if you're talking about RWD. I am in Canada, 2011 on all LS are AWD. I had to live with that even though I choose to drive RWD sedan, but AWD sports car.
