The folks running it were originally from Jeep... Jeep spun it off and eventually GM picked up the distribution rights (don't know if GM owns them outright or just the distribution rights???)... at any rate, jeeps are known for electrical problems (I've owned a couple, I can tell you first hand it is true... have others that have had electrical problems... consumer reports said the same thing{have not checked in years, things might have changed})... back to the point, the original design team came from the same folks designing jeeps... prob. not the case anymore, but might have electrical problems down the road...
As stated above, they aren't big on the inside... there is a lot of room shoulder to shoulder, however there really isn't too much leg room. The back seat is tighter than you might think.
the inside isn't luxury at all... very "GM like"...
The tires are huge!! I have no idea what it would cost to replace them, however I can tell you they aren't the $100 a tire variety...
Not sure what motivates you to purchase the car (the looks, power, interrior, etc.???)... look around, check out the competition before you sink that much into the car (although I understand you can get "resonable" lease rates, because they hold their value well)....
It drives/rides like a truck... a buddy at work has one... ask a question and I'll get an answer for you... (fwiw, he really likes his)...
