Trouble finding the perfect car?

I'm having trouble trying to find the perfect car that matches my exact specifications.

I'm looking for a lightly used entry level 4-door sport sedan.

I've been mostly looking at Infiniti G37, Lexus IS-250, BMW 3, Volkswagen CC, Mazda 3 or 6, and Honda Accord V6. I've also been loosely considering the Hyundai Sonata or Kia Optima with the 2.0T.

But every car has a drawback that I don't like. I don't want to buy a car and end up not liking it.I've made that mistake in the past and I really don't want to go through that again. It was just a complete fiasco.

While I like the G37 for the horsepower and value… The ride and power delivery is crappy to me. It feels so unrefined and it feels like you're riding on a park bench. It just feels a step below everything.

I like the Lexus IS-250 for its good looks, premium/elegant looking interior, compact size, reliability and resale value. But it's lacking in power. It feels about as fast as a Corolla. I wish the G37 had the same level of prestige, features, interior elegance, and refined power delivery the Lexus had, but I wish the Lexus made the same amount of power as the G37.

The German cars have great driving experience but long term reliability is an issue. I need something that is not going to require trips to the mechanic every week.

The Korean cars are nice, but how long are they going to last me and what are they going to be worth after another 3 years. That's an issue.

It's a tough call. What do you suggest
Added (1). mccoyblues: I'm looking at a used last generation Lexus IS. Probably 95% of IS's made in the last generation were the 250. Finding a 350 is like finding a needle in a haystack and even then most of them were RWD. I live in a snow belt state as well
