You would have to add the solar yourself. At best you would only add 2-3km for 1hr of full sun. On sunny day maybe 15km of range. However, if its a short trip to work and back or if you only travel a few days a week that would be enough.
Unfortunately they only sell that model in Japan. So Nigerians and Canadians are out of luck :( Well....at least for a few more years. In Canada I can order "old" models from Japan by Canadian law...but have to be at least 15 years old. In Nigeria....no idea how that works :)
Oh, too bad. Have no ideas of importation of cars here but it is strict though. You have know somebody that knows somebody that can help out. Connection is the key here.
Almost the same in Canada.
You don't actually have to know someone but there is so much paperwork and legal process that you either (a) have to know someone who has done it or (b) do an awful lot of research and hope things go well :)
Different world...
....Same problems :)
Have a great day
