it does not have a good gear box, its more like driving a small car like lancer 1.3 ltr. if you go for 6 cyl its much better.
interior is ok, a/c not that effective.
i don't know about resale value and as far as spare parts are concerned average price but not that cheap and you don't get conterfiet parts for all.
the dealer offer a good service and if anything is not working and if it is under warranty they will replace for no charge.
doesn't require too much maintenance as far as i know
but the fact that it is hyundai i would advise you to be carefull.
