Can I ask why you want to use a manual car?
Modern automatic transmissions are far better and efficient than manuals, unless you are going to do serious off roading or truck driving.
Hahahaha. You almost made be fall off my chair. You don't really believe that do you?
Automatic transmissions are so good they mostly use them for racing. No wait. They use manual transmissions. They use manual transmissions because they are not as good. No wait. They use manual transmissions because they want to win the race and they are better in just about every regard.
Sure, if you are a crap driver or can't be bothered getting any proper skills you might be better off with an automatic. It's easy right? You don't even have to think or plan your gear changes. If you have even a moderate skill level you can get both better performance and better fuel economy than an automatic transmission.
Don't see a lot of F1 cars or V8 Supercars on the public roads. Do see a lot of little boys trying hard to play out fantasies of being a F1 or V8SC driver and failing.
I have a Nissan Altima AUTOMATIC which is a bigger car just averaged 6.4L/100km between Wellington to Taupe to Napier to Wellington. You need to catch up with the capabilities of modern vehicles.
