A 72 4door is not worth that much, as the cutlass was very popular in the 70's. In fact, oldsmobile broke the 2 million car record in 75 or 76(I dont remember). and the 4 door cutlass was seling well. So, they're (or were) common. Anyway, for a little good news. If you want to get into your car, you can go under and up. Pull out the fan, and you can get clearance. The go up, ubolt the latch with a wrench. That should do it. If not, get ahold of me.
