I’ve often thought the perfect Cannonball car would be a VW Phaeton, either the W12 or the V10 diesel.
The diesel will do 500 miles on a tank (if driven relatively sensibly) and has an electronically limited top speed of 155 mph. The W12, if you remove the limiter, will exceed 186 mph. Both of them, at first glance, look like a Passat…
