The '63 Lincoln convertible has the same number of doors as the 1934 Auburn 652 Y, but twice as many (  = more ) door posts that the hinges are attached to.

( on the Auburn all 4 doors are hanging of the B-post, on the Lincoln, the fronts are hanging off the A-post and the rears are hanging off the C-post.)

[Wendax]

The Fiat 500 has a smaller trunk than a 1963 Lincoln convertible.

The Ford Five Hundred's badge uses more chrome characters to say, in effect,the same thing the Fiat 500's badge says

Tommy Ivo's Showboat dragster's engine(s) are more visible than that in the Mada Autino

[Allemano]

I guess the Autonomobile is a little more silent than Ivo's Showboat dragster. (but of course I don't know for sure)

[Otto Puzzell]

This Hurst Oldsmobile 442 has a bigger shifter than the Autonomobile

[Wendax]

The Colani parade truck has a larger dancing area than the Hurst Oldsmobile 442.

I forgot we already had the fiat 500/126, so this link might not be OK.

[metalshapes]

GM's 1959 Firebird III dream car has more fins than the Ultimus.

[Paul Jaray]

The Mizar Air-Car Flying Pinto was an ( even ) less succesfull experiment than the Aerocar
( it killed both its creators in a crash )

[DeAutogids]

The Aerocar was worse at flying then the Mizar Air-Car Flying Pinto (despite it's name)
