1000whp Trackhawk would be on the list.
The car constantly reminds me of just how perfect it really is... flawless looks, functionality, comfort for 4 adults, hauls the groceries, tows my trailer, lays rubber, runs 10s... 28mpg highway...
The reality is that there were so many made, and will be available in the used market for decades to come, I'd be foolish to think something better wasn't right around the corner and if not I could just buy another one (or 2).
Each car that I've ever missed before it couldn't stack up to it, but they were unique in their own way. I'll miss this one when the lease is up, but it'll hopefully be replaced with something better.
