Definitely a bad deal. I haven't done my research on LT's but if you go back a couple of pages myself and another posted our fully loaded premier deals and that should help you get an idea on where to start.
FYI you should be emailing several different dealers to get quotes. My first quote...
That's a pretty good deal for now, I think. I got a deal similar to yours with total end costs almost identical.
MSRP $43510 (has the fast charger)
$2500 Drive Off(including 1st month, taxes, registration etc.)
15000 miles/year
Payment $355 after taxes
36 month lease.
