I actually have a Mercury tracer and it is one amazing little car it has some of the best and worst things in my opinion. But if you ever get one you get a strange attachment and feel like the car is more than it really is. I've had it for one year and it only has 46,000 miles on it it gets great gas mileage and has plenty of power for city driving and oddly enough this car does great cornering and on dirt it really handles well the interior is very simple but looks nice and the car over has a great look some of the parts are a little iffy though but it is a Ford and they have been known to have problems like that but fords also take the best beating and just keep going.
I really like the engine it just sounds great all the time and runs very strong when its tuned well the car has amazing suspension and really takes a beating I've driven my car sideways for most of the time I had it. This car stays flat through corners and really holds the road when you want it to.
It really would be great if the could fix the wiring and overall hi end speed. The car really moves well but needs to be refined. Also it doesn't have a very rigid frame so in a hard corner the whole frame twists just a bit I would still give this car a ten on the scale of fun and practical.
