in my area ... back in 2004 I think ....... a guy modified a 2nd-model Corvette (the classic one with 4 headlights) into a modern version with all the modern touches but retaining all the classic styling. Only ever saw it on a local tv car show that was never repeated.
Rather what Mazda did with the MX-5 -- a modern MGB. Pity they never did a hard-top hatch version like the MGB-GT

So many possibilities with 50's / 60's classics, I too am surprised that more isn't done.
Always liked the Impala rear-end so that 789 does look nice

Nice job on your T-bird Limo, sequoiaranger :)
