2013 4dr Sedan turbocharged 274hp 2.0L I4
6-speed shiftable automatic FWD		 Kia doesn't have the best reputation, though I get the sense that it's slowly improving. Speaking personally, I would have laughed at the idea of buying/leasing anything from Kia even three years ago. However, in that time, I've had two: a 2011 Kia Sportage EX and, now, a 2013 Kia Optima SX Limited. The mediocre brand image is a unfortunate, because if you slapped another make's emblem on this car, people would probably be absolutely gushing over it. As I said, I don't think their image is improving, though. see full Kia Optima review
2007 4dr Sedan 161-horsepower 2.4L I4
5-speed shiftable automatic FWD		 poor trade in value but intend to keep long time due to great warranty; Kia discounting cars in USA to gain brand penetration; much better priced here than in Europe for the same car. see full Kia Optima review

2004 4dr Coupe 238-horsepower 1.3L R2
6-speed manual RWD		 My personal biases show here being someone that drives almost exclusively European cars. There is nothing I hate more than under lighting and flame kits on exhausts and the RX-8 fall smack dab into that category. see full Mazda RX-8 review
