This is how they might look...

Please note that I've tried to capture the spirit of various languages, with some twists for entertainment value. Don't take it personally if the car I selected for your language of choice isn't what you'd like, this is purely for entertainment

Fortran

Sturdy and dependable, though not particularly maneurverable or sexy.

Lisp

After all these years, no other car has vertical doors (which also kind of look like paretheses).

C

Still the best systems programming language 40 years later.

C++

Because C wasn't tricked out enough.

Perl

Larry Wall was commanded by god to create this language... Rumor hasi t that the cryptic syntax contain clues about the life of Jesus after the ressurection.

Visual Basic

Loads of fun to drive endlessly around the Microsoft app track.

Python

A stylish ride, though not the fastest or most maneuverable.

Haskell

How do I drive this thing? Despite being older than many languages on the list, Haskell is more modern in most ways.

Lua

Cute, efficient, and becoming very trendy.

Java

Not pretty or fun to drive, but solid.

Javascript

Originally a go-kart much in the vein of Visual Basic, Javascript has become a reasonable language in its own right. It still has a lot of warts and is marginally functional outside of its original domain.

PHP

Initially popular because it was easy to install and let users embed code in web pages rather than write CGI applications. Now it is the purple bat van of programming languages. I'll leave the interpretation of that statement up to you.

Ruby

Similar to Python in many ways, though arguably slightly more maneuverable and less elegant.

C#

Based on Java and slightly more modern, but in some ways less solid.

LuaJIT

Though not a language in its own right, LuaJIT is an amazing technical accomplishment and that little car is just too cute not to share.

Clojure

Lisp, tricked out for the JVM. The Delorean monster truck is probably overkill, but you get the idea
