@Louisa. This is great information on the motor type and also the value of these replicas. But one thing stood out in your post about "I don't work on cars". I thing the understanding that these motors are old technology might assist. Tuning Carberators and distributors. Valve adjustments every 3,000 miles. A good VW mechanic can manage these and should be found before a purchase of any replica with a VW motor.
I write this not to detour you from considering a replica, but rather to give you knowledge and understanding that though it is a 2007 build, it is not the same as buying a 2007 Mercedes SL which could be found for a lot less money (turbo V12 model even).
