OK you can have direct drive in to the diff(Needs to be geared right) and then will not need a transmission or you can go via a manual transmission, 1st gears is useless and most do not use it .. some people do not even use 2nd. now this is the fun part, if you have the time and money you can make the car AWD. You have 1 motor running the rear wheels and 1 running the front wheels ...
If not the Holden ... I would try a Mazda MX5 as they have a pretty low drag rate or even Fords Lemon the Capri ...
MX 5
Lemon
IMHO I would go the Mazda, it is Japanese Made and you know it will last and have no problems .. Fords just suck and the Capri was a real Lemon in Australia.
You can pick up MX5 MK1 in Japan for about $AU100 now days .... I do not know what the price would be in Australia as I left the place 10 years ago and have not been back.
Me ... Married Twice, only just divorce the 2nd wife last year after 8 years of marriage ... After leaving the ADF in 1992, became a bodyguard in Taiwan then South Africa, Australia, then Chad and the Ivory Coast as a Merc, back to Aust, bodyguard in Malaysia, Indonesia, back to Aust then Japan as a bodyguard back to Australia, then crap work for the WA Government in the Police Force on the Multi-Novas for about a year before telling them to shove it because the pay was crap, Security Manager for a few clubs in NB and plain clothes armed cash escorts for a company in Thornlie .. once again ticked off and decided enough was enough and moved to Japan. Did 6 months in the pit(Iraq) as a PMC and decided the money was not equal to the BS and the threat of being blown to bits with a IED by some paedophile worshipping twat, so back to Japan, Security Manager and bodyguard for 2 Gentlemen's Clubs until I retired from the protection game in 2007. Open a Aussie Pie shop until 2011 when the wife and I divorced, she held all the licenses, so that was finished ... Now have a new company as I hold my license to produce cars .. at the moment only 3 employees ... but like Tesla give it time and we will get bigger ...
As for a EV from Perth to MR ... I would be trying to get ya hands on Toshiba SCiB Batteries .. these suckers are in the Mitsubishi i-ev and the Nissan LEAF and what I will be using .. SIM-DRIVE in Japan used them both in the Elica and their current vehicle with a range of over 330ks
