Difference Between TRD Off Road and Sport

Hello - I am relatively new to the world of Tacomas, but enjoy off-roading and have decided I want a Tacoma as my next truck.
I am looking at a more expensive 2007 TRD Off-Road vs a cheaper 2005 TRD Sport
I am willing to buy the more expensive one but with comparable miles and years, I want to make sure that the $1000 price different is worth it.

 

How many miles on each? Only difference in the two are cosmetics and an electric rear locker on the TRD off-road.

 

are both 4x4 or pre-runner?
I personally like the seats in the TRD-Sport, i like the hood scoop too even though its just cosmetic.
More info plz
got any links?

 

If you don't know the difference then the Offroad is not worth it.

 

Does the rear locker make a big difference, I know that some rear lockers are "anti slip" and don't make a big difference.

 

It'll make a difference when you absolutely need it. It's a locking differential, not an anti-slip function. Both tires turn when engaged. If it's a 4wd, it'll only engage in 4lo, but if it's a prerunner it functions in 2wd. I opted for the OR because I liked the rear locker and wasn't a fan of the hood scoop on the sport.
