We bought both of our new trucks this year. I used True Car pricing for both as a starting point and went down from there as much as I could. Both of our new vehicle purchase prices were well below True Car pricing. But it did at least establish a base line for negotiations. For those interested, there's a site called CarBuyingTips.com that has a nice spreadsheet that I've used for years in helping calculate costs and offers. I've actually taken the original spreadsheet and modified it to make it more functional for me. It has saved me more time and money than I could have ever imagined. Of course, in the spreadsheet, you work with the numbers you can find regarding MSRP, dealer cost, holdback etc... The only factor that gave me pause using this spreadsheet has been the unknowns as far as factory to dealer incentives, volume discounts and the like. The spreadsheet is laid out nice and is pretty self-explanatory. Give it a try. And, as a disclaimer, I'm not affiliated with CarBuyingTips.com in any way, shape or form.
