I'm digging the Nismo 2020 rims is there an aftermarket rim out there that looks almost similar? I see a seller on Ebay has for $6500 Seeing if an aftermarket option is available and cheaper?  

Thanks

What year did the autographed engine plate start? I thought it was 2014 but I've seen a 2013 with it. Is there a way to find out which one the 4 hand built the engine for a 2013 if it doesn't have it? Thanks

I'm looking at a 1 owner clean, carfax, solid red 2012 with 25K miles. Are the updates on 13, 14, and 15 make me regret getting a 2012? I'm finding it nearly impossible to find a solid red one owner with low miles, clean carfax, not too many mods in a 65-70K price range.

I know the 15+ has updated head and taillights that I can easily swap out for. 

Thanks in advance.
