So I've been looking on Euro Car Parts website for 72ah batteries (as apparently you should fit to a GTI)
and theres:
Exide 72ah, with 720 CCA @ £81.54
or
Bosch 72ah, with 680 CCA @ £86.34
both would be less 25% discount of course from Euro
however, which would you go for, considering the Bosch is more money and but has LESS CCA ability!
:-)
