You found a $20 bill -- now what?
Auto detailing can make it feel like you have a brand-new car. But a complete detailing job can be pricy, Lowell says. The best bargain on four wheels is to get just the interior done. You're now driving around with "the new, fresh smell and the vacuumed interior."
He estimates that it costs about $17 to detail the interior and vacuum out the trunk.
And for a few extra bucks, you can hit the automatic car wash the next time you fill up.
