I like the list by Tantibus on page 3. Nothing wrong with Reba, but for working on the car I would take her out of my mix and for a little country influence I would add in Junior Brown.
Maybe add in some 70s trucker songs like six days on the road, convoy, White line fever, nitro express and Wolf Creek Pass.
I would need to add some Frank Zappa to the mix.
Definitely some Judas Priest & Kiss.
Some high energy blues from Junior Wells
Cmdr. Cody and the lost planet airmen
The Kings, shift into Glide
Throw some Zydeco into all that and I'm set.
