Ok... I couldn't help but reply to this thread. I'm just slightly more obsessed with cars then with macs (ok... that might be an understatement...) Anyway, I'm currently a college student with no money (I have a mazda 3 that I saved for ever for) but I've got a car obsessed dad who actually has money so I've had a chance to drive alot of the cars on your list.
Anyway... if I had 35000 to burn I would hands down recommend the honda S2000. My dad has a porsche, and honestly, I can't say the extra money is worth it. THe S2000 is an incredibly good deal, and drives really nice. There's something kind of strange about revving it to 8000 but you get used to it. Its kind of minimalist also, which I really like... but its not quite as eye-catching as the germans. If you really want a roadster I'd get it. By the way, you do not want a lotus elise unless you're completly insane. I thought I could put up with a lot in a car, but let me tell you, nothing can prepare you for the noise and stiffness of that thing. Its an incredible car, but only for dry weekends durring the spring
Sedan wise, the acura TL is nice, but I wouldn't get it if I were you. I can't tell you how many of my friends parents have them. Its a nice design but its too common to be eyecatching. That, and its front wheel drive. Torque steer is not fun. Its especially heavy with the manual... auto's ok though. Really depends on how you're going to drive.
BMW's are really really nice. Nothing drives like them... and there's a reason they're called bavarian MOTOR works. Its not that they are particuarly unrealiable, its just that they are expensive to fix when they do break. It also seems to depend on the model. One of ours is never in the shop and seems to be great. The other one though is a mess, and has eaten a couple of thousand recently. I think they're worth the risk though. As soon as I graduate and have money to burn fixing cars I'm going to buy an old E30 M3. My parents had one when I was growing up and I loved it.
As for the Jaguars... I'd pass if I were you. Personally, I think the only one in your price range (The X-Type) isn't nearly as pretty as the larger ones. Its a ford mondeo underneath (sort of like a europeen taurus) and the engines aren't great from what I've heard. Reliability's better... but still not up to the level of the japanese or even the germans. I've never driven one though, so take everything I just said with a grain of salt.
So... all that's left is the infinitis. I'm quite fond of them. I had one growing up and it was really nice. I really like the G35. Its getting redesigned slightly for this coming model year. It's going to look a bit more like the M35. It has that great3.5 liter VQ series V6 that Nissan seems to be tuning for everythign now. Its especially sweet in the G35 and it should the 300 horses mark in the new one. Its also rear wheel drive, which to me is a real plus. It might not be if you live in the north, but there's always all wheel drive for that.
I can't comment on the Audis and Benzes. I've never drive an Audi (i've always been more of a bimmer guy) and the only benzes I've driven have been big ones. I'd try them out. Just be warned that their reliability (especially the audis) is not good. Even worse then the BMWs.
Sorry that went on for so long. Go drive all the cars. You seem to have a resonable sense of whats out there. Go drive them and figure out what you like. Then read the reviews and see what you might have missed during the testdrive.
One more thing. How about used. You could pick up a used E46 M3 for not too much more then what you're looking at.
