None at this time.
We got the Sienna XLE Limited a month ago and we couldn't ask for more. It's the top of the line model and checked off every option it had (Limited Package #6). I consider it the most luxurious minivan on the market right now. All safety features available are standard. Leather, power everything, power sliding doors and rear hatch, park-assist sonar system, Laser-Guided Cruise control, HID Lights, Moonroof, JBL Premium 6-Disc In-Dash CD Changer, and 17" Alloy Wheels standard. We even went and got the Optional GPS Navigation System and DVD Player. All those features aren't available on other vans. It features a car-like ride found on the Camry. Power is abundant and can get us onto the freeway at full load with ease. There's plenty of space, lots of cup-holders, and all are conveniently placed. Price, however, was a bit high. At $38,456 MSRP, it's not cheap. We got $1400 off.
I forgot to mention that the only thing I disliked was that the standard JBL Premium Sound System wish 6 Disc In-dash CD Changer was replaced with the same system except a single-disc feed. It was because the GPS Navigation took over the same space and the CD Player and Cassette player is hiding behind the navigation system. The navigation flips down to reveal it.
