I spotted this thread, and have tried to bite my tongue, but I can't stay out of the pool. The OP's use of word "beater", as well as many other follow on posters, is just wrong!
Here's the totally-official definition of a beater from my own personal dictionary: "Inexpensive, used car that is sufficiently dinged up that you a) don't care where you park it, b) don't bother to fix it if it gets nicked or dented, c) would never even contemplate having it detailed, much less washed, d) wouldn't freak out if it broke down or got stolen - would just replace with another beater."
A new Gen 3 could not possibly be a beater. Not sure if a used one will ever be either. A new Smart, Volt, Leaf, etc. is also not a beater. Nor most of the other less-expensive-than-an-S cars mentioned in this thread. Those are "second cars". Correct title of thread IMO should be "who would buy the gen 3 as a second car to preserve their S". Sirs and madams, you are disrespecting the real beater!
Examples of beaters:
a) 1968 Ford Fury III station wagon that I inherited from my parents with 80k miles on it, drove to 120k despite putting crease in front grille and radiator... stop leak worked fine... and passed along to my brother who drove past 200k. Nobody ever fixed the radiator!
b) 1996 Camry my daughter bought last month for $1000 so she would have transport she doesn't worry about parking on NYC streets... though she's a crappy beater owner because she still worries.
