There is almost nothing this car can't do, and the stretched L version makes a perfect rolling office for the businessperson (or rap star) on the go. Up to $80,000 or mire for a 9 year old car..with 90,000 miles.. expensive to maintain, very powerful and if you have the duckets it's a great car

ive been told the motors are problematic do u know about that or the engine specifically

Nothing problematic about those engines. They are high performance, and with any high-performance such as these, a 12 cylinder 6.0L 438HP engine there are always going to be one issue or another, but there is nothing notoriously wrong with them
