I've driven on the highway a few times, trust me I get my fair share of bugs!! I pretty much wipe down the whole front everday lol! The airfilter is suprisingly clean, so far....

I drive my beater around atleast a few days a week if I have alot of errands to run.

My first car, 1992 chevy beretta gt 3.1l v6 has 114k on it, great beater with A/C!
