Do NOT use solid core wire on a car or anything else that moves and vibrates and it doesn't matter if you are talking AC or DC for this rule. The solid is far more likely to fracture from vibration, more likely to wear through the insulation if it is laying against metal, and is acutally harder to work with especially in the large gauges you would be using for ground wires - you would almost need a pipe bender to bend it.

Shocker is off base on the AC skin effect vs. no skin effect on DC for our discussion here. Wires are rated by American Wire Gauge or mm squared. A #1 AWG in solid or stranded is going to have the same cross section so the resistance is the same. A stranded wire will have a slightly larger diameter because you can't pack round objects with no voids but it isn't a big deal at the end of the day.

Welding cable is fine to use. Tinned welding cable would be even better but that is about impossible to find unless you have the factory do a special run for you.
