The ideas about no maintenance or repairs
There is a lot less to maintain, not sure I heard anyone say "no repairs".
The other question you have to ask yourself is "would you rather buy a 6 yr old ICE car or a 6 year old Tesla in 6 years?"
I cannot imagine an ICE car being cheaper to repair and maintain. Not to mention fuel cost. In UK, forget it, it's 130p/litre now, in 6 years it will be 150p/litre. Costs me £300/month just to commute. It wont be getting cheaper due to lower demand.... Not to mention replacing the alternator/ spark plugs/ DPF/ belts/ fuel pump / radiator (since there is a grill and it can be holed by stones). Oh and the annual engine oil change.
Which means more demand for 6yr old Tesla, which means higher price...
There are literally no Model S cheaper than £33k in UK right now, as soon as one comes up it gets bought. That's for a 2014/15 model with old AP and all the issues those old models had, such as dodgy handles.
