I do not know why people think the dealer can look into a crystal ball an know if the customer is going to like the way their TT handles.
I also do not understand why people blame themselves when they find the TT and TV combination does not tow as expected.
Anything that involves "feel" is so subjective; what is swishy to one person may not be an issue for another.
It all comes down to how much does it bother you and how much are you willing to pay to change it.
I found the sluggish performance of my 200 hp V6 annoying enough that I traded up to a 356 hp E-boost. Sure I would like to have an even bigger TV, provided someone else was willing to buy it for me.
