Not TV series, but I watch a couple of Youtube channels that are a running series of car stuff.
Vice Grip Garage is a guy that finds old cars sitting up for years (some for decades) and revives them where they sit and tries to drive them back to his home base. He started in Minnesota but moved to Tennessee for better climate year-round. Good clean entertainment.
A similar themed channel, based in Texas, is Flying Sparks Garage. A husband and wife team works on various projects....cars, trucks, tractors, boats, planes ans a semi. They just finished a multi-episode series reviving an 80's era Peterbuilt rig and converted it to RV status instead of commercial so they could pull the 40' enclosed trailer (retired Red Cross blood drive trailer) they've been converting to a race car hauler/camper rig.
If you're a car guy, it's good stuff.
