I have a subaru sport for more info please check my post: http://racingrivalsforum.ciegames.com/forum/the-neighborhood/unsupported-player-trades-sales/3284091-testing-waters-subaru-wrx-sport-for-trade
So far the highest offer is a bundle of cars: Zonda, Gt concept, bmw gt2, ford gtr, and z4. Please do not waste my time offering a simple cars for it, if you don't know the value of the subaru do a reseach about it.
These surveys do not work!. I been playing this game for a long time done over 30-40 surveys and got 60 gems 1 time only. They claim the surveys are always incompleted or the info given is not good. Overall do not wasted your time.
