I know nothing about leasing figured, but 10k off MSRP souinds like a good deal. You are financing the depreciation of 12k over 28 months so that alone is over $400/month.
I live in Tyler and the last I checked the dealer here had an Imola Cab still on the lot. mikepile.com They even have a $100 off coupon on their website. Dunno if they will give the $10k off MSRP as well- it stickers at $64k+
Don't forget your CCA discount if you have been a member for a year.
