Not sure who DDM is, but is their kit custom-fabricated to fit our cars?
Do they have slim ballasts to fit inside the headlight bucket?
Does their kit come with step-by-step installation instructions, with photos specific to the NSX, and including warnings of common mistakes?
Has their kit been installed in HUNDREDS of NSXs?
I understand some may be soley looking for the best price- good for them- but most NSX owners aren't in that camp. This is an iconic car, so when upgrading I look for quality parts, a vendor that has a good reputation and is prominent in the NSX community, so WhiteNSX's "expensive" kit fits my bill.
