...ar make had "ford" somewhere inside its name e.g. "bedford". Safer general practice is
Auto[Auto$name %in% c("ford", "toyota"),]
or similar using subset().

Auto Data in the ISLR Package
I did not care to load the packages -- small reproducible examples are
preferable, as the posting guide suggests.
But, if I have understood correctly:
See, e.g. ?subset
Alternatively, you can read up on indexing data frames in any good basic R
tutorial.
Cheers,

Toyota cars from the Auto data set in ISLR R Package. Thank you very much
in advance.
Please use the following code to see how is the data look like.
install.packages("ISLR")
library(ISLR)

head(Auto)
with many thanks
