re: Anyone here have a corporate car or car allowance??

I get mileage, which isn't bad for 50-100 miles a day, but I wouldn't recommend it if you're driving a ton like you are implying.

If you can't get a lease, drop 6-10k on a used hybrid and get mileage. At least you have a chance at extra money that way, and won't have to deal with all the BS every week. I wouldn't use your current personal car.
