 I've driven a dolphin grey quatro A4 
for about 7 months which now has 
14,000 miles.  The only car I measured 
it up to before purchase was a BMW 
325.  All in all I am very satisfied 
about my purchase however the driver 
side window sometimes rolls back down 
on its own when I push it to roll up.  
Other than that no problems worth 
noting.  I feel very safe in this car 
for me and my family.
