so I need a front bumper for my 2000 Jetta. It is atlantic blue, a
color which was only used for one year and thus almost impossible to
get used. Checked some online vendors (after the recent discussion
about RockAuto) and found:

ECSTUNING: Genuine VW/AUDI (1J5807217JGRU) $318.43
Busdepot $317.36
some vendors on Amazon from $140.00 to $300.00
RockAuto (CAPA certified) $76.79

The part from RockAuto is the least expensive (and is the most
expensive from their site (starts at $49.00) as being "CAPA
certified").

Now my question: how accurately will this bumper fit? Does anybody
have experience with how well the parts fit from RockAuto or is it
"you get what you paid for"?
