It was unveiled at the 2007 Knott's Berry Farm National Kit Car Show. 2008 GraberCars La Bala. The la Bala is a homebuilt car designed and constructed by Steve Graber. The car is built on a tube frame chassis and is designed to fit a Toyota MR2 drivetrain in a mid-rear configuration, though most front-wheel drive engine configurations can be mounted in it. It is built using an early model Toyota MR2 powertrain. The reality is that there are many other donor choices available that may actually be better suited to lightweight vehicle construction. At this point though, construction is far along and won’t change in the original prototype. La Bala is a low-compromise, from the ground-up, new car.
