Kustoms are cool, it's still recognizable as an Elky, but my feeling is is that if you are going to chop up/change/restore any old and somewhat rare (now) car, it better be done for good reason, and it better be done right. You don't trash a 63 split-window Vette and make it into a Funny car dragster, or cut up a 'Cuda convertible and make it into a Monster Truck.
Those 2 elkys pictured look to have some serious love and attention put into them, most likely the motors and chassis upgraded and strengthened, bodywork fixed right, those cars stand a better than average chance of being around in another 50+ years for the owners great-great-grand kids to drool over.
To me, that's a really good reason to do what they've done, and I can get behind that idea.
