Here is what I would do...
Tell them that is doesnt have sport pack and that should lower price, check to make sure car fax is clean, tell them that you have to have a Lotus dealer inspect the car and do an ECU dump. See what they say...
Also, here is one FS on here, same price, same miles, WAY more options...and best part is that its a owner on here...
