I will say that I've gotten a quote for an entire conversion kit that includes a Tesla Model S battery pack, motor, controllers, custom couplers for about $20k for my Jeep Wrangler. It's obviously not going to get good range since the Jeep is a giant box but all things considered I paid about 7500 for my old jeep to restore so $20k on top of that is basically a brand new Jeep (and quite a bit cheaper than brand new high end electric vehicles and hybrids). So, not completely out of the question
