is this a good price for a 2007 Boxster S

[RaceCarDriver]

looking at a dealer demo. It's a 2007 Boxster S, with 1,900 miles (supposedly it's the sales manager's demo) Car stickers for $63.3k and they will sell it to me for $54k. Is this a good price?

I was thinking about leasing it. On a 60 month lease with 12k miles a year, a total of $5k out of pocket, my payment would be $717 a month (this payment includes sales tax)

Is this a good lease payment?

thanks
