Im looking at getting an enthusiasts JUST for the LSD, the other options are just a plus but I can do without. Should or would I be better off getting a base model then buying a differential later on? Nismo has an awesome LSD I assume? I'm looking to go cheaper at the moment since my credit isn't "established" enough and need the dad to co-sign, I'm trying to make the price look as pleasing as possible to him since he thinks I'm crazy for wanting the car. Any suggestions appreciated, thanks!
