This is a kind of random question, but I'm interested in opinions, so here goes.

Back story:
On March 6th I was hit by a car. I've been riding a rental bike, theoretically paid for by the insurance company (I have to pay up front and then be reimbursed), since the crash as I wait for my regular commuter bike to be repaired.

The bike shop I'm renting from is a very small affair, and I rented directly from the shop owner, who told me he had planned on selling the bike for $450, but that he'd happily rent it to me for $150/week until my bike is repaired (he was also thinking about keeping it as a shop rental bike). The rental bike is a used Cannondale H600 Hybrid.

It's been over 6 weeks since I rented the bike. That's $900 for the rental so far, and the shop working on my normal bike said "Maybe this week," but made no definite promises.*

Question:
Should I see if the shop I rented the Cannondale from will just give me the bike, since by the time I return it to them, they'll have gotten more than double the intended sale price for it?

* My decision-making process on choosing this shop is a whole 'nother post. Let's not even get into why it's taken almost 2 months to get my bike repaired...
