I have a good relationship with my Service Manager, Assistant Service Manager, and GT-R tech. Like Scott said above, I initially got a blank stare from my Service Manager when I said I wanted to meet the GT-R tech. However, they accomodated me and I found him to be quite likable. We hit it off immediately. Now, everytime I come in, the tech comes to the front to greet me, as well. I've offered tips in the past for what I thought was service above and beyond, but the offer always declined, saying it was against the rules and they could lose their jobs for accepting. I've even "threatened" to bring them a 12 pack of their favorite brew, but then I was told they don't drink. Oh well, I tried.
Anyway, they're great guys and always treat me right. I'm lucky to have found them.
Incidentally, I have known this particular Assistant Service Manager since 2004 who had always taken great care of me. I had a 2004 350Z Track model that I took to this particular dealership for service routinely. I had a horrible buying experience with the Z and swore that particular dealership was never getting one dime from me for service and maintenance. I tried this particular dealership for service and hit it off well with the Assistant Service Manager and stayed with them ever since. Even with my "meager" Z, they treated me right. One day in mid 2009 I brought my Z in for its 60k maintenance and got to BS'ing about the GT-R with this Assistant Service Manager. I had never seen one in person. He told me they had one on the showroom floor and brought me inside to see it. After I went home all I could think about was that car. That night I told my wife, "Honey, I think its time we both got new cars." Since she was going to get a new car as well, the answer was a resounding "I agree." The next day, when my Z's maintenance service was done, I traded it in on the GT-R. The Service Manager oriented me to the car and I left my beloved Z behind and drove home in the GT-R.
Of note, I didn't have my checkbook with me. After completing the paperwork, the dealership let me take the car and just asked me to drop off the down payment check "at my convenience;" I dropped it off the next day. The entire purchasing experience was far more pleasant than I experienced buying the Z. I've been friends with the Service Manager ever since. I've also been friends with the GT-R tech since meeting him. They've always treated me well and consequently I've steered a lot of business their way. The way I see it, since they refused a monetary tip, new business = tip. The people I've steered their way to my knowledge have also been quite satisfied with the service they have received.
And for my wife, a week later she got a brand new 2009 BMW 335i with the Sport Package. Now we're a paddle shifter family.
Also, to the OP, ask your dealership to install your exhaust. They'll appreciate the business and will keep you in mind when it comes to favoritism in the future. If the tech is cool, he'll enjoy the opportunity to wrench on your car to improve it, rather than just another routine diagnose/repair. That's what I did and I believe it had a very positive effect on our business relationship.
And like Scott mentioned above, I've met Chris, the GT-R tech at Fontana Nissan. He's a great guy, as well! And for those of you who don't know, Scott at Fontana Nissan is a Time Attack racer extrordinaire. He was my instructor at my first track day.
