In my case, depreciation has been pretty horrible. It's costing me more per month to drive a Focus ($426/month) than what my folks are paying to lease their $60,000 diesel E-Class ($315/month, $0 down, 24 months).
sales price + tax: $20,700 ($300 below invoice minus all incentives)
private party value: $14,300
DEPRECIATION = $6,400 over 15 months and 17,000 miles
It doesn't help that Ford has been flooding the fleets with Focii and that there are a lot more incentives now.
