Does anyone here know of a good place to service an NSX in the Toronto area or north. I have a 91 in need of some engine tuning. I also need to replace the AC/heater module. It heats and cools only. Other additional controls do not function. I priced this a few years back and was quoted about $1,700. cdn. Thanks for any info. I have owned this car since new and don't want to give it up. It's bullet proof.
