End the saga.
Get very specific facts and call someone who sells them all.
First, is your car a TQC or a 1989-91 Coupe Quattro? What year?
Next, ignore the dealer prices, they are ludicrous.
Finally, call someone who will figure it out and stand behind it.
I bought mine from Euro-tire (call 800-information, or 201-575-2515,
ask for Chris). They sell all three. Ijust paid about $250 for
all four shocks for my 1991 90q20v, BOGE TurboGas. Bilstein had a
front application but no rear. I think Koni was the same. Both
were about 2x the BOGE price.
Whichever you have (TQC or later CQ), you have a rare car.
Make sure you deal with someone who knows the difference. We can;t
do much more than this on the list. Chris can, and E-T's prices
are about 30% (or more) off list.
BTW, the job takes about 4-5 hours plus full allignment. The
dealer obviously included the allignment in their flat-rate
Be sure to do strut bearings at the same time.
