Avalon for the win!
 I bought my '97 avalon 7 years ago for a whopping $800 with 150k mi. on it.  The previous owner had used synthetic oil since he purchased it new and I followed his his advice.  It currently has 255k on the odometer.  It has zero leaks, zero throttle delay  and pulls as hard as it did as the day I bought it.  Now the Avalon may not look like much. And it's not that fast off the line.  But from 50 to 80 it will surprise you.  Since I live near the beach in florida the paint has taken a beating.   However, In 7 years, aside from the regular tires, oil and belts, I've replaced the radiator, water pump and alternator.  All together I've spent maybe $1000 on non preventative maintenance.  The engine and transmission could be classified as military grade they're so solid.
