So......
After doing much research, I've decided not to buy a Kia Rio RX-V (Cinco).
Not one review I've read had much good to say about the car, its based on the Ford Aspire (which barely Aspired to be a real car, hehe), and I was right, the 1.6 is the Hyundai Accent Gsi engine (according to Consumer Reports magazine).
There isn't enough data to show reliability for this car, nor a parts network if things fail, hmm. I'm scared to buy it now, after all, to me, its a lot of money!!!!! The warranty is good, but after reading a lot of headaches about claims, (which I'm sure its all the dealers fault though), I'm convinced things won't go my way.
I think I may opt for a Toyota Echo hatchback (not available in the US, but you guys will get the Scion, :( I want one!!)
I hope the next generation Rio (based on the new '05 Accent platform) will be a better car, they've already got the right engine, just need all the rest of the good bits Hyundai has to offer.
Cheers, and thanks for the advice.
