I've been looking at them and I'm really liking them; every thing about them really. Also, they're not too expensive (30 000 - 40 000) for a "luxury" car. What do you think? Do you think they are nice? Any advice?

If you like the way it looks, and the other aesthetic aspects, you should get it. All such “luxury” cars (lexus, Acura, Infiniti) are well built and have similar technical specifications. If I were you however, I would go with one of the more established lines (Mercedes E350, BMW 530) for seven to ten thousand more.

Acura Tl Is A Great Car And Consumer Reports Ranks It As The Number #1 Upscale Sedan To Buy. Consumer Guide Also Ranks It At The Top Of Its Class. Its Good To See That You Have Great Taste In A Car. The Only Other Car I Would Consider In Its Class Is The Infinity G35. Only Because I Live In Wisconsin And We Get Alot Of Snow And The G35 Comes With All Wheel Drive. But If I Lived Anywhere Else, I Would Go With The Acura Which Is A More Refined Vehicle. You Will Enjoy It..

I have a friend who owns one and he is highly satisfied.

I would say go for it, but be sure to check out the competition. The Lexus ES330, with its new version (ES350) coming out soon, can be had for a song compared to its sticker price.

I picked up my Infiniti I35 brand new last year for a song, but I doubt you will be able to find any brand new I35s left in the country.
