Buying someone leased boxster

[peakpro]

I have located a low mileage boxster that is being leased by the seller. The lease period is nearly over.

Since it is low mileage he is hoping to make a profit by buying car at the end of the lease and turning around and selling it.

Are there any downfalls from my end? We would both need to pay tax and of course I would not buy unless he held the title..

anything else?

thanks
