So you want to manufacture an electric motor, some batteries all the wiring and associated bits that go with it deliver it all, and then remove and safely dispose of the running gear from my car, how long is it gonna take to earn back the energy deficit you just incurred making and delivering all that lot compared to the energy my car uses in fuel minus the energy needed to charge the batteries i have to fit???? it dont even cut emisions by an awful lot as we dont get much of our power from clean sources so your just moving the pollution.
As for my coupe not being more special than your sedan, thats your opinion, i guess you would prefer an Athena poster to the Mona lisa but thats your opinion and your allowed it, i guess your sedan is a nice non polluting economy vehicle? or is it a large overweight modern car full of energy using things like electric windows and air con?
My coupe is my daily driver and does less than 5000 miles a year, as are many of these older cars that are getting chopped in for scrap so even if they ARE more polluting and less safe, they are on the roads less than the people with more money and bigger more modern, more expensive cars anyway.
All this scheme is doing is either persuading the sort of people who have to drive an old car to go buy a new one on credit they probably cant really afford, or those who have an older car hanging around not doing an awfull lot anyway, and those are the cars that would end up being found under a shett in 20 years ideal for restoration.
personally i'm happier to collect my beautifull woman in my beautifull coupe and go out for dinner getting admiring glances from all the guys in there modern and anonymous sedans.
