Not sure when Toyota changed from the 4speed auto to the 5 speed for the Hilux , don't get a 4 speed auto , also check when Toyota sorted the injector problems , a 2013 model would be the best bet .
Believe me it's worth doing some good research before spending your cash
Sorry Don't know how to remove post so removed content. Some interesting ideas though. I might go for something more eco friendly though. Like a Hippo!
