Both are V6/ 4WD? I'd get the Limited. I really think with Toyotas it's milage that matters more than age. You'll like all the luxury stuff in the Limited.
Potato - potahto. If you get 100 replies, there will be no consensus. You'd just better drive 'em both and decide on which merits are important to you.
What about things like maintenance done, tires, any accidents, carfax, etc?
What's the Ltd got that you have to have vs the newer SR?
Likely the 08 because I don't need the extra bells and whistles and I don't like leather seats. Ther4e is also more to it like others have said. More bells and whistles = more to go wrong.
09 sport edition V8. Mica. Keep looking they are out there.
The hunt is half the fun. Only you won't find one is if I beat you to it. I'll sell you my 08 SE V8. 85 K babied (2W) miles and a 9 out of ten in and out. 10 being new.
