Rated
based on 3 customer reviews
I bought car used with 100,000 miles, Interior is cheap for a car that cost this amount of money new, Its not leather its' pleather(plastic) my little dog slides like she is on glass on it. The GPS stinks, Now the good part, 38.5 miles per gallon on the freeway, and about 26 city, very nice stereo, handles great, I have the fold down seats, great for long cargo, sun shade in the back keeps car...
I LOVE this car! fuel mileage is great, power is wonderful, takes corners terrific. I've put nearly 20k miles in six months and overall could not be happier. ONLY thing I'm not crazy about is the GPS, and the electronic "files" you have to scroll through to make changes... very cumbersome.
I love this car. Great mileage and a 6 cylinder turbo diesel engine that feels like an 8 cylinder on steroids.
