Is resale value something important to keep track on?
I find that it doesn't matter that much

The common perceptions?

Parts are expensive and difficult to find. The i30's parts are fairly similar priced to genuine Civic or Corolla parts, if you've maintained one you'll know these aren't exactly cheap any longer. Service centres are definitely more expensive than a UMW-T service centre. OEM parts are available and like for like they're mostly around the same price too not because Korean parts have become cheaper but more along the lines that Japanese car parts are  no longer as cheap as they used to be. Parts difficult to find?? Perhaps that might have something to do with you living by a keyboard only??? Here's something for you to bite on, vast majority of Kias and Hyundais are sold with 3 years free servicing you do save quite a bit there.
