Purchased my '91 NSX back in December as some of you may remember. I have been extremely busy and have not had the smog done yet. It is still out of California compliance. I believe it is due to the modifications done on the motor. Anyone out there have a recommendation on a good shop in the San Francisco/ Marin County area? Need to bring it into compliance as my time is freeing up and I would certainly enjoy actually driving it,.... It does look good in the garage though,.... Someone mentioned last month about 'Don' at Top of the Hill, Daly City. Any input on that advice,...Thank you in advance for any assistance,....
