Here's my take:
Having a TL as a courtesy car obviously has its perks: superb acceleration combined with the luxury experience. The TL has a lotta options: handsfree bluetooth technology (which can be set-up with my V551), dual climate-control, butt-warmers, and so much more. What it lacks is rain-sensing wipers, auto-headlights, and ALR (which Mazda3 offers).
Pros for TL:
-Superb acceleration - you step on it, off you go. No need to wait for VTEC to kick in. And it's supposed to be a Honda?!? I like the VTEC feel... too bad you cannot find it.
-World-class braking - no fading here. I thought Mazda3's have superb brakes... until i drove the TL. They're very edgy, however. It took me a while to get smooth. And it's very difficult to come to a complete stop without any jerks.
-The looks - wow! It has by far the sweetest interior one can imagine. The blue lights comfort you.
-HIDs - unbelievable! I never thought that road could be this bright: going down SFU hill, i could see everything! Mazda3 clearly is way behind in terms of headlights, even with its' fog lamps turned on.
-6 airbags - did someone say safety?
-Heated seats - as soon as RN sat in the car, he could feel his bums burning. Enough said.
-Sound system - superb! DVD-quality, indeed.
-Acura quality - heaters work with "right now!" command! It heats up waay quicker than the Mazda. Quality wise, Acura > Mazda, no questions asked. But you are paying for the premium...
Pros for Mazda3:
-Weight - weight, weight, and more weight. Weight advantage is HUGE!
-Gearbox - no autotragic transmission here. =)
-A bit more features: auto-headlights, and rains-sensing wipers for starters.
-Price - you can get two top-models Mazda3 for the price of one TL. Enough said.
-Gas consumption - requires 87 Octane... and is cheaper. A lot cheaper!
-No torque steer! A big issue with the TL. Ugly.
All in all:
If Mazda3 is a ballet dancer, then the TL is a fat lady. I kid you not, that car is HEAVY. You can feel it. Going on a curve, it inspires no confidence. Sure, it is very, VERY quick, but that's about it. Yes, it has a lot of nice features, but hey, i prefer dancing. I'm young (22), and i'd much rather be with a ballet dancer than with a fat lady. (No offense.) ^^
Sure, the "fat lady" has got a lot of class, experience, and money, but for me, i'd prefer a ballet dancer any day. Mazda3 handles better than the TL! (And i've only upgraded the tires: stock tires are only good in the dry pavement.) So if the stock Mazda3 (with ultra-high performance tires) can outhandle the TL, imagine what the possibilities are when i put on the SCC springs. =O
Basically, the TL is for older people. I wouldn't be caught myself driving a TL. TSX, on the other hand, handles a lot closer to Mazda3. It's a little bit quicker too (than Mazda3), but i still wouldn't pay 13G's more for a TSX. Mazda3 should appeal to the young, or to the young-at-heart crowd.
I love my car sooo much more. Love it for the price i paid, for the little gas consumption, and for so much more. Mazda3 is the best bang for buck right now.
As i said earlier, the TL is for older people; people who just want comfort, and occasional speed off the line. But as Donald (M_Speed) said: going fast off line is boring. I will be returning the TL tomorrow... and getting another car. Hopefully something that handles a lot nicer.
Bring on the curves, please! (Plain power doesn't please me.) I'll have my Mazda3.
