I am looking to replace the heater core in a '91 CQ. By far the best prices I have come up with are from www.autohausaz.com VAG/Meyle is $57.30 and Auradia is $82.79. Everyone else is in the $120.00 to $140.00 range. Does anyone have any experience with autohausaz.com and/or either of the above brands of heater cores ? TIA Jeff
