Which car will have the best resale value by 2020?

If I were to buy (cash not finance) one of the following:

2013 Scion FR-S (great mpg, a bit higher insurance)

2009 Honda Civic Si (good mpg, good insurance)

2007 Lexus is250 (eh mpg, good insurance)

The fr-s has 37,000 miles
The civic has 75,000 miles
Lexus has 85,000 miles

So by 2020 we're talking at 12k/yr. (6k in 2014)
Fr-s = 103,000
Civic si = 141,000
Lexus = 151,000

Which car will have better resale? The fr-s will cost more insurance wise and is a bit more initially but the mpg and good reliability may pay for itself… After all its a Toyota (Lexus is too but I think parts are a bit more expensive right?)

Well I can't say for sure but my guess is the Civic Si. The Si has street cred within the street racing community. The FR-S could become a little outdated when the newer models come out. However the Lexus is probably the most expensive out of the three so it should be work the most later. Also with gas prices and advanced technology people may not want to by the Lexus when newer green + economical cars are on the market also with lower prices, just like Mercedes and Audi are doing with the CLA and S3.

Might be the parts of fr-s become quite economical because the technology is changing day by day and 2020 is quite far. While your car would not run too much so in my point of view, fr-s is going to pay you more in 2020.

Civic will have the best resale.

You should NEVER buy a car based on resale value. By the time you are done driving a car, if you are smart, resale won't matter. If you drive at all the next 6 years, the last two will be well over 100K.
