I've always tried to differentiate my cars in one way or another, whether that means full window tint, after-market wheels & tires, lift kits, or whatever it takes. Over the years, I guess I've rubbed off on my wife. We recently picked up an '07 ES350 with just 30,000 miles on it. My wife's only complaint was that it looked just like every other ES out there. No need to say anything else...
Here's where we started:
After tinting the windows:
After adding a rear spoiler and 20" wheels (8.5" wide) with 245/35R20 tires:
While it may not be everyone's "cup of tea", we love the way it looks. Obviously, we lost some amount of ride comfort (though before this my wife drove my Expedition so it's still a huge improvement) but we gained a fair amount of handling. It still doesn't handle like it's on rails, but we lost alot of that floating feeling it had before. We've had no issues with rubbing at all. And surprisingly, even turning the wider tires, it's still averaging about 28 mpg in mixed city/freeway driving.
