This car was completely done by me and my teammates in the past when we ere in engineering school. Completely done with infusion, the new teams now use prepreg with carbon molds and an autoclave since they have a sponsor to give them acces to the autoclave..

The best advantage if you want my opinion is that it also let you make your layup all with dry cloth and place everything well and form your cloth to your mold with vaccuum before getting dirty (infusion is very clean, no drip anywhere), if you already have a pump,
I'd say you should start doing some tests since you only need some flow media and some tubing and clamps to get started (since you already have a setup for bagging wet layup). I guess you use peel ply as well? However, you need to calculate well the quantity of resin.
you need a resin with low viscosity also so it wet all the cloth well. repairing a missed part is doable with a partial bagging and a second infusion but the look is affected a lot most of the time.
I never bagged wet layup parts since we only did the molds with wet layup. But just using wet layup is a hell of a dirty job, resin is dripping everywhere and i hate that
Note that i'm an electronic guy not the best composite guy but i understand a lot since i participated in the fabrication of these cars.
So i guess the next question would be : "is infusion difficult with core materials
like foam" ? I almost exclusively use honeycomb , so infusion would be a No-go for
me ; but Lots of people still use foam cores , (can't understand why though) ; except
for price ?

You have not got a clue.
