1. I have a V8 engine. I am German. I do not achieve higher than 20 miles per gallon on the highway. Some of my standard features include air conditioning w/dual-zone climate controls, interior air filter, tilt/telescopic leather-wrapped steering wheel w/radio controls, cruise control, heated 8-way power front seats, outside-temperature indicator, and a universal garage door opener. DVD entertainment is available, but pricey at $2670. I am NOT a competitor to the Porsche Cayenne. The letters of my model name are the initials of a comedian. I love to off-road, likely because I am good at it. Can you guess who I am? (Make, Model, Trim)

2. I am a full-size SUV, though not nearly as big as my competitors. I am German, I am luxurious, and I am powerful. I achieve 20 miles per gallon on the highway. Standard features of my least expensive trim include air conditioning w/dual-zone climate controls, leather upholstery, tilt/telescopic leather-wrapped steering wheel w/radio controls, 12-way power front seats, and cruise control. I have three available trims. I have a 280 horsepower V6 engine. Can you guess who I am? (Make, model, trim)

3. I am more luxurious than the Audi TT, Porsche Boxster, and BMW Z4. My price is under $70,000, but not by much. I am a convertible. I am NOT German. Can you guess who I am? (Make, model, trim)

4. I am likely the least expensive car to have a standard navigation system. I have a 6.0 liter 320 horsepower V8 engine. Besides a navigation system, some of my standard features include a rearview camera, premium sound system, heated 6-way power front seats, remote engine start, universal garage door opener, cylinder deactiation, cruise control, air conditioning w/tri-zone climate controls, leather upholstery, leather-wrapped steering wheel, and satellite radio. Consumer Guide Testing says that my handling is mediocre. Can you guess who I am? (Make, model, trim)

5. I am a very luxurious and powerful full-size SUV. My base price starts at just over $60,000 (as of January 30th, 2009), though I'm definitely worth the money. I have an engine that's more impressive than almost any other full-size luxury SUV. It takes me a mere 6.5 seconds to get to 60mph. My standard features include air conditioning w/tri-zone climate controls, cruise control, leather upholstery, heated front and 2nd-row seats, 14-way power front seats, memory system, remote engine start, universal garage door opener, power liftgate, outside-temperature indicator, compass, and premium sound system. Options include DVD entertainment, navigation system, rearview camera, power sunroof, and power-retractable running boards. I can tow 7,400 pounds. Critics give me better reviews than they give to the Mercedes-Benz GL450, which is my direct competitor. Can you guess who I am? (Make, Model, Trim)

1. Mercedes-Benz ML63 AMG. Not exactly what I would consider to be a decent off-roader but ok.
2. Audi Q7 3.6FSI
3. Mercedes-Benz SLK55 AMG. If that were the correct answer I would argue against it being more luxurious than the Audi however, not that there is much information to work off of anyway aside from an opinion and a price range.
4. I'm going to guess the GMC Yukon Hybrid, it is the only 6.0L V8 I have found that only makes a measly 320hp. I found plenty of smaller motors that made even more and still got better gas mileage.
5. Cadillac Escalade ESV.

I take it you're a fan of Luxury "SUV"s, yes?
