Wow, glad they're both ok.
I'd find out what they liked about the Lexus and then let that guide you. Did their car have much technology? How comfortable were they with it? This is actually what I find is the "arms race" in luxury vehicles. If that's actually a net negative, you might want to steer them to a low milage older luxury vehicle (not German). Plenty very very nice LS400/430/460 out there. If they have to go newer, don't write off the Hyundai Genesis. It's as good as the rest and maybe better in some ways.
Yeah it's simple.. they liked the Comfort lol. Nothing else really matters. That's why I'm basically asking if there's anything out there in the same level as the E350 or Benz E-Class with the same ride we should look at. The LS is nice but they cost twice as much so not sure they'd want to buy a much older model to stay in that same price bracket (the LS would probably need to be a 2011 or 2012).
The Hyundai Genesis is a total piece of shit. I had 2 friends who bought one. Both pulled the 'No, no man Hyundai is better now and these cars are a great value' reason for buying them.
Friend #1's car had a bunch of minor problems and eventually developed some electrical issue the Dealership could never figure out that caused it to stall even at speed. This freaked him out so much he got rid of it. Never again he said.
Friend #2's car had a huge amount of problems. Almost nothing worked and once out of warranty stuff just started breaking. You'd get in the car and he'd have to tell you not to touch half the stuff.. like the Sunroof, etc. I was also unimpressed with the interior quality (knobs fell off or broke, etc), the fact that the AC never blew cold air despite him having it serviced multiple times, the one time the GPS took us on an insane wild goose chase.. or the fact that the Bluetooth didn't support Bluetooth audio (the fuck?). Most of the time i'd drive us in the Scion xB because overall it was a better ride experience. Eventually his kid wrecked it.. never again he said.
So yeah no I just can't find a compelling reason to roll the Korean dice, not when they aren't really that much cheaper than other options.
