Does it really make sense to rent a car for a road trip when you have your own?
I’m sure it makes perfect sense in some cases. If the car you own is incompatible with road trips (Unimog comes to mind), is a horrible gas hog, or just too valuable or too unreliable to be driven long distances, a rental is a perfectly good alternative.
To find out if it works other times, I picked a hypothetical driver John who owns a clean, two year old Lexus ES 350, a perfectly reliable, efficient and comfortable car. According to Edmunds.com, each mile in that car will reduce its value by 7.5 cents, so a round trip from Miami to Disney World (about 600 miles) will drop the car’s appraised value by $45, and take it closer to the next dealer service. If Lexus charges about $80 every 4,000 miles, that’s another $12, for a grand total of $57.
What can John rent for the $57 he saved by not taking his car on a two-day trip? Around the Miami area, not much. The cheapest rental for two days is $86, and perhaps with a coupon or another promotion he can get it down to $57, breaking even on his combination.
However, for a week-long trip totaling 4,000 miles it would make better sense: John is saving $380 dollars by leaving his car home, and for about $150 he can get a low weekly rate on a full-size sedan.
If John leases his Lexus, none of the above math applies – in a leased car the miles are either “free”, if you are well under the annual limit of the lease, or they are very expensive, 20 cents per mile or more. If your actual accrued mileage is getting close to the lease allowance, taking a rental to that long trip may be a very good idea indeed.
