While car shopping, I built a spreadsheet of vehicle costs. Here is a graphic presentation of that data. Costs are based on Consumer Reports data and 12,000 miles per year.
The cost per mile is nearly identical between the family sedans. That is largely because the largest cost (40%) of car ownership is depreciation.
My 09 Fusion V6 with everything except AWD costs are lower because I paid cash (no interest) and paid $10k less than retail. I could have gotten the same low cost per mile on a Jetta TDI, but it would have been a 2006.
Nobody was offering deals on the Prius in December ’08/Jan ’09. In most cases, dealers were charging above retail. Now I’m hearing of people getting $5k discounts on them right now. A recent news article was titled, Hybrid sales go from 60 to 0 at breakneck speed. With the tax benefits, available discounts, and low cost of ownership, the Prius might be worth considering right now.
