WhyMe
If it's the car you love and has all the other goodies, color inside / out, options and style (IOW you have fallen in love) ... you could easily just say whats on your mind --- You don't want those items on the car therefore see no value in them.
ie; "I like the car otherwise and might be willing if to negotiate a fair car price and/or potentially pay 'cost' for those items if you can show/prove cost or I'll consider a 50% break on those line items."
The general idea most have is The Buyer wants to beat up the salesman or dealer for the best deal and dealers want to build up or retain profit through customer deals.
If not going internet, tell them you want to respect their methodology and time and expect that as well ... to get a fair deal that works for everyone.
If those cars are still rolling in, ask if you can snag one off the carrier before it goes to prep and the add on's Mop and Glo shine etc...
My last car deal on a pre-owned was an Infiniti 2+2 coupe. I was within $1200 to $2000 of where I wanted to be and they knew me and dealt with me on 5 previous deals through the years. A nearby store had a silver automatic, I liked this one as deeper graphite color and a 6 m/t. * I did not announce that. This is your leverage.
They only knew I was shopping two very similar cars. I told them the numbers had to move closer to my liking and I said a simple calculation of the mileage to value that the other car equated to as better would be a match if we came in at $1600 less. That would close it for me and we did the math showing what I stated. Done !
I was fair and measured about the process and kept my word with no tricky stuff by them or me. They knew I was 'in the business' years before and had played it straight in the days when internet sales was the new big thing. Keep everything logical , no squirrely left-brain stuff !
On my latest new car deal, not much wiggle room on an outgoing '17 to new 18's coming in.
Already $5000 off msrp and exactly what I wanted, I waited til F&I and knew they would push for extra warranty add. The 17 had a 3/5 and the 18's went longer , maybe 7/70k or something. Thing is, its the same car, motor and everything so I pretended to be very pleased. The same car and motor I was getting was as good as the 7/70 - simply proving to me there was no reason buy extra.
Then I told them if I consider this car will be mine for 6 - 10 years, what might they offer for an incentive to get extra long coverage ? I ended up getting 10/100 coverage for a very fair cost and I really did want that piece of mind.
Good luck !
