Sugestion... call up Edrick at WestCovina Toyota -- or Steve Gantz at Carson Toyota (or both) and ask for them to fax you a price quote on the TRD Ext Exhaust (GTS) and also mention what happened today... see if they FAX you the price that you're looking for
it wouldnt hurt to ask
then take this fax with you to the dealership you went to last time and tell them that they are going to loose you money if they dont sell you the exhaust... atleast this way you take the upperhand by letting them know, that you know exactly the price they are getting the exhaust for and you're sick of them dicking you around like this.
basicaly they dont care how far you drove or the fact that you were in traffic for a long time... they just want to make a sale...
remind them that you are rotating parts through their store and if they dont sell the exhaust system, they loose the "number" that they would make with thier suplier.
just a sugestion
