the only problems with evos are

there are lots of them
there is allways a new one coming out thats better and making yours lose more money
they cost a lot when they go wrong

having said that they are a great family sports car which you can use every day an escort coss probley not realy not because it cant do it it will just get damaged or nicked because they stand out and look special.
As for them not selling if you have a nice one you will sell it easy and for strong money thats what i think any way
