 I bought my optima (4 cyl, 5 sp. man.) about 2 years ago with 41 miles. It is now up to around 87k and still going strong. It had been wrecked before i bought it but I haven't had a problem in the world! I love it! Most of my miles are highway and I average around 26 mpg mixed, but my husband has gotten as much as 31 out of it. Its got plenty of pep through 2nd gear, but you loose ground when you hit 3rd. About the last two months I've been noticing a noise when I am stopped with the car in neutral and the clutch released, but it stops when I press the clutch (think its a throw out bearing). Fantastic car!
