1.5 inch lift shouldn’t be a problem.
8 week turnaround time is very unrealistic though. Ford recently said hybrid delivery would begin in January (10 weeks away). February - March would probably be optimistic if you’re just now ordering. I would say April-June is entirely possible.
X-plan is invoice - 0.4% +$275 admin fee. It also caps all dealer added fees to a $100 document fee.
so you doc fee should only be $100 instead of $150. Some of the other “registration fees” May also be dealer added fees (as opposed to state DOL fees) that you may not actually owe under xplan...
