On my 2007 Lexus ES350, while backing up, l can not see the back end of my car.I am tall, so that is not the issue.I've also tried raising the seat all the way up with my head touching the roof.

And ofcourse, no, l did not get the navigation system, or else l could've used the rear view camera.l guess, l can also install a reverse sensor to resolve this issue.

However, l was wondering if anyone else has experienced this issue?

l have not had that problem because l actually have a cool car.Its a 2007 Lincoln MKZ that will leave your little ES 350 in the dust.

l have test drove the new ES350 & it is sooooooo smooth. l did not noticed the rear view problem because the ES350 l tested had a rear view camera & a nav system. You can install a rear view camera or back up sensors by yourself though. l would suggest a camera because it can be hidden more easily. l have see ones that come with a LCD monitor built in the rear view mirror which is pretty cool. l have also seen a rear view camera kit at Costco but it looks kind of cheap.

Also, it is not true a 2007 Lincoln MKZ can smoke the Lexus ES350. The Lexus has more horsepower, more torque, & better fuel economy. l am also sure that the Lexus is quieter, more fuel efficient, more reliable, & more technologically advance than an American car. Also, BigBuck16 should not called it ''your little ES350'' because the ES350 is actually bigger than the 2007 Lincoln MKZ. The ES350 looks a lot better than its previous generation ES330 & it definitely looks better than a 2007 Lincoln MKZ. l think it is embarassing to say a 2007 Lincoln MKZ is better than an ES350 when the Lexus is more powerful (Lexus has 270+hp, MKZ has 260+hp), faster (Lexus goes 0-60 in 6.8sec), more reliable (duh.), more fuel efficient (Lexus gets 30mpg on highway & MKZ gets less than 27mpg on highway), cleaner(Lexus is an Ultra-Low Emission Vehicle (ULEV II)), safer (Lexus has a knee airbag, adaptive headlights.), & more luxurious (a lot more high tech features, too long to list.).
