Who all has had the dealer install some goodies at the time of sale? What did have installed? When I purchase my new Mustang I want to have LCAs, 3rd link at a minimum and hopefully Boss intake, springs, and GT500 mufflers. One local dealer said they would install Roush LCAs instead of the Ford Racing pieces. Not sure how much they will negotiate on these aftermarket items and what I can expect to pay for installation. I know it may cost a bit more. I am eligible for X plan pricing so that along with any rebates will help offset the cost of my aftermarket toys. My reason for doing it this way is 1)Warranty 2)Don't want to fight with wife over spending money on my new toy 3)I want it all now! Thanks for your anticipated feedback.
