 You would have to be INSANE to buy an Audi A4.
I drive mine 12,000 miles per year TOPS and have
done $3,000 worth of repairs with less than 60,000 
miles on it.  I've had bad wheel bearings, 
timing belt (which will destroy the 
engine if it ever breaks), water pump, 
radiator hoses, mass airflow sensor, 
and now the thermostat.  The dealer 
charges $400 to replace the 
THERMOSTAT!!!  (a $30 part).
 Even in peak operating condition, this 
car would get killed by a Honda Civic 
in a drag race, and gets lousy gas 
mileage.  Do not be fooled by the Audi 
badge, these are Volkswagens in 
disguide, except the maintenance is twice 
as expensive.  Get a Lexus.
