Don't do it!
 I bought a demo thinking this is the "Ultimate Driving Machine" boy was I wrong. Everything is too expensive, the car has been in the shop 7 times since I bought it. The sound system is just plain bad, the DVD player doesn't work and it took forever to figure out how to change the clock or even the radio station. That is unless you want to read the 97 page manual which tells you how to do so. Is it a head turner -  yes without a doubt. But in today's economy- when you take in to account the price of gas, insurance, the overall cost of owning it I say "Don't do it!!"
