Why buying you looking to buy a car..Yes, blue book does help estimate the value of the car..but its the popularity rareness. How often do you see a mr2 driving around on the road? If you want to see how much these car are worth..check mr2trader.com. You'll be surprise how much people on there is asking for. 6-15K for these car easily. The fact that this car is completely stock, also make the value up there. Yes...mods can add values to car..and it also can depreciate the value of the car. Same goes for civic's, intergra's...their kbb value are low..but people are willing to offer more money for it. Peace!!
