Since options are one of those things that sales only like to talk about when therir product has it, I can'tthink of any one place that would have that info.
One of the big issues in car sales is that we can go to one dealer and find a price but then we may go down the road and find another dealer who "appears" to have the same product for a few dollars more or less.
But if we get the printed specs for each, there are often small differences in what looks exactly alike? You often have to have the printed window stickers to sell what a car has.
Something as simple as different grade fabrics is an easy one to miss when we think we have matching models. So each dealer has the choice of how many of those little hidden items he thinks will help him sell or miss out on a sale.
Some feel they have cheap buyers, while others feel their customers want only the best!
I had Ford family folks and it was a trick every year when folks went down the road 30 miles to buy but came to the local garage to complaint about what they DID NOT get!
