The whole "green notion" is kinda warped. I still have my 1992 Camry. It's a 4 cyl. 5 speed manual that gets about 35 mpg. It was cheap in 92 and has been payed off since 97. Probably put a few grand in it over 20 years for repairs and routine maintenance. Has 200k on it and still going strong. Simple is always better.
