Japanese cars are more popular where I live so all of these are Japanese. I'll start from the oldest:

1999 Toyota Celica. It's a bit dated-looking now, but still pretty good for a late 90's design. Even has a bit of flame-surfacing going on too:

2002 Nissan Teana. The oversized headlights and flat body panels scream early 2000's but overall the car still looks fairly OK for a design that's over 10 years old. More timeless-looking than modern-looking perhaps:

The interior was made to look like a lounge:

2002 Nissan 350Z. The design takes a few styling cues from the original Audi TT of 1998. Would still look fairly modern today with some minor changes:

A good example of the early 2000's aluminum fad (again inspired by the TT of course):

2003 Mazda RX-8:

2003 Honda Accord. In fact, the new one for the European and Japanese markets doesn't differ too much from this one styling-wise:

2006 Honda Civic. Looks almost cutting-edge even today. Amazing for a car that's nearly a decade old:

Anyone know of any others?
