Faults:

Nothing yet, but it's still new.

General Comments:

This car handles well and the ride is very smooth.

The power hesitates for a brief moment when the accelerator is punched; possibly due to the automatic transmission.

The trunk lid profile tends to somewhat block your rear-view when backing up.

Lots of great standard features that are options in other manufacturers, such as air conditioning, electric door locks and windows, tilt wheel, CD player, cruise control, 8-way adjustable drivers seat, and dual front and side air bags.

I was originally shopping for a Spectra, but I found that I could negotiate a lower price for the larger, more plush Optima. (I paid $12,895 and they even threw in a couple of tanks of gas, free car washes and an oil change!)

My mechanic told me that parts are quite expensive for the KIA line, as there aren't many aftermarket parts available yet; although I haven't personally looked into this aspect.

Manufacturing seems to be done well, with no seam gaps, etc.

Well engineered with a very solid feel.
