Bud, unless you buy a Caddy, or an L-daddy, you aint gonna get any smoother... Drive it around and see what you think.
Gen 1 & 2 ES 300's have emblems on the tail. (gen 3-4 Camry)
No non-BWM car comes with Angle-eyes... There were two kits on ClubLexus.com, but both members got banned for hocking their products, and fighting with each other.
The frameless windows are actually superior in suppressing noise. The sunroof is the same way. My '93 has been outside every day since I got it last year and the other owner left it outside 1/2 it's life in Destin Florida @ the beach house. The seals are A-1, no leaking. (Especially if you use a rear rubber conditioner on them before you wash the car)
Don't worry about them breaking in a wreck. IMHO it's an advantage they're frameless. One of the real big Audiworld member's got T-boned in the drivers side by a semi-truck on the highway & flipped & all kinds of shit. Instead of shattering, the frameless window just bent inside the car and stayed in 1 piece.

Strong glass

Notice it's 50-100% thicker than what you normally find too.
No idea where they put the space. I can tell you that surprisingly, the interior is shorter in an ES, because ES's were standard with a moon roof, and optiond as no moon roof. (more sold with than without) That cuts about 1-1.5" off head room. (If you're 6ft and under it won't matter)
I can tell you it's definately not in the engine bay

Typical Toyota (and now USDM) It's not built for "small hands", it's assembled in a way to put the maximum amount of stuff in the smallest area. (Everyone does it now, so no Jap stigma's anymore please)
