Re: New Owners/National list of Z Shops
Does Lingenfelter and Doug Rippie still work on our cars?
Any new info on Vette Doctors in NY or Tony’s Corvettes on MD? Not sure I would include Corvette Mike in Anaheim, CA. although in a pinch they would do, unless someone has better info. This should be a list of people who really know what they are doing.... H :cheers: |

Re: New Owners/National list of Z Shops
Robbie’s Corvette Masters is located next to Rogers Corvettes. Rogers is a Chevrolet dealer that only sells low mileage and excellent condition Vettes of almost any year. He has sold to me and many other ZR-1 owners. He recommended Robbie for mechanical work.

Yet to be an owner, and surely a novice in the purest sense, but any experience with West Coast Corvettes in Anaheim, CA?

Re: New Owners/National list of Z Shops
Precision Motive in Hayward Ca has worked on ZR-1s in the past but don’t know how extensive the Z knowledge is at that shop. I do know they put the automatic in the Steel Blue 91 with the Shinoda body kit floating around and worked out all the bugs,not sure who did the plumbing for the nitrous setup. The owner of the shop Pat Hendrix is a great guy to deal with and he’s had this shop for years.

Re: New Owners/National list of Z Shops
Possibly the better solution is to list two categories. Vetted known level one “Master Shops” and level two “Basic Competency” Shops. Based on member feed back we can move shops between the two or out altogether.

Re: New Owners/National list of Z Shops
What’s the story on South Georgia Corvette? Still in business? They did a lot of Z work 10years ago.

Re: New Owners/National list of Z Shops
This just posted over on CF regarding the presale inspection on the low mile 90’ for sale in SOCAL. A good example why these shops need to be vetted.
H “My experience with Corvette Mike was terrible..I went to them as I wanted to have the best shop work and document on my low mile (17,000) ZR! car I purchased. They misquoted, charged extra, when the work was done and I picked it up, only to find out they didn't test drive it . it didn't run any better...THEY DIDN'T EVEN TEST DRIVE IT AFTER PLENUM/INJECTOR SERVICE..... they apologized and wanted me to give them a chance to correct the problem. I did.....They told me it was a bad TPS, (TPS was replaced with new delco by me) only to find out that the TPS connector was them problem ..This was a 1600++ repair for injector and plenum removal and they didn't test drive it..(I know, hard to believe)......The worst part was when service manager (carl) tried to tell me he he spent 4 hours diagnosis and it should cost an extra 4-500 dollars.....Since then I have found many people have had issues with Corvette MIke...I would not recommend this business as they have no accountability” |
Re: New Owners/National list of Z Shops
Sounds like they screwed up, but not sure that you want to test drive your Z! I always pop the hood and do a visual inspection and then tell them you’ll be right back. U road test it and either give them a thumbs up or get into to them to fix it right!
BTW-tell them there are no greasy finger prints on the engine and you don’t want to see them when you pick up the car! Sent from my iPhone using ZR-1 Net Registry |
Re: New Owners/National list of Z Shops
Updated...
I’ll ask again, Does anyone have a status on the following shops? All of these were once top notch LT5 Shops. South Georgia Corvettes, Thomasville, GA. Doug Rippie, Waverly, MN. Lingenfelter Performance, Decatur, Indiana. For tier two, any new info on Vette Doctors in NY or Tony’s Corvettes on MD? Based on some internet searches... South Georgia Corvettes, Appears to be out of business. Doug Rippie, Still shows an LT5 package but no maintenance or repair. Lingenfelter Performance, no reference to anything C4 let alone LT5. Vette Doctors, Shows an LT5 package, possible maintenance and repair. Is known to work on Z’s. Tony’s Corvettes, no specific LT5 reference. Is known to work on Z’s. |
Re: New Owners/National list of Z Shops
I understand that Tony's Corvettes in MD has a mechanic who is LT5 certified. Also Sport Chevrolet in MD also has a mechanic who is LT5 certified.
As for me, I stick with Wazoo who are all better than LT5 certified! |

Seems it is based on the personal opinion of others who are not LT5 Certified ;) Or it is based on the percentage of times you guess exactly what is wrong with an LT5 in the first step of a diagnostic process based on the insufficient information provided by an Uncertified LT5 operator :) Having said that......a group of guys not LT5 certified may as a group be LT5 Certified and that is why I have suggested Jim and the WAZOO guys on a Sat are LT5 Certified (I have never heard of a complaint) :sign10: |
Re: New Owners/National list of Z Shops
How does one become certified, enquiring minds want to know.

Re: New Owners/National list of Z Shops
My understanding was back in the day Chevy dealers who were lucky enough to receive a ZR-1 had to send at least one mechanic for special training to be LT5 certified. Not every Chevy dealer had one on staff. I do not know where the training was held. I would assume most of them are now retired.

Re: New Owners/National list of Z Shops
There certainly was a GM LT5 training class with an extensive curriculum. I too recall dealerships had to have trained technicians to sell ZR-1s. Not sure if it was called a certification. Weren’t there even little trophies technicians got for completion?
Probably long since discontinued by GM. H :cheers: |

The WAZOO LT5 certifying process straight forward and starts with a critical evaluation of a candidate’s skills on the BBQ grille. Next up is stocking and maintaining the beer cooler. 21st and final step is cam timing while blindfolded with one arm tied behind the back. Sent from my iPhone using ZR-1 Net Registry |

Re: New Owners/National list of Z Shops

Re: New Owners/National list of Z Shops
Any more recommendations? I can’t believe that is it...?
Can we get this thread up as a sticky...? So we can continue working on it and make it more visible to newbies. Thanks H :cheers: |

Re: New Owners/National list of Z Shops
I think it's been over ten years ago or so, but I worked on a project that included preparing a list of "ZR-1 shops." My research was based pretty much solely on the inputs from members of this forum as well as those from Corvette Forum and possibly whatever else I was able to find on the web. There was no confirmation done on the validity of the recommendations and this is over ten years old so it's possible some of these shops no longer exist, but here is the list (take it for what it's worth -- this is not a personal recommendation from me as I have only personal experience with one shiop on this list -- ZR51/Bill Boudreau, who I would highly recommend):
Name, Location, Phone, Website Bank's Chevrolet, Concord, NH 603-224-4055 Brady's High Performance, Willow Street, PA 717-283-0056 Ebert's Engine Service, Abita Springs, LA 985-960-2483 Freedom Cars, Nashville, TN 615-254-5252 Guldstrand Motorsports, Burbank, CA 818-558-1499 http://www.guldstrand.com Haibeck Automotive Technology, Addison, IL 630-458-8427 http://www.zr1specialist.com Henderson Performance Technologies, New Braunfels, TX 210-867-6286 http://www.hendersonperformance.com Jim Watson Performance Concepts, Lawrenceville, GA 770-978-7400 Lingenfelter Performance Engineering, Inc., Decatur, IN 260-724-2552 http://www.lingenfelter.com Pacific Northwest ZR-1, Vancouver, WA 206-755-0976 http://www.pnwzr1.com Pine Belt Chevrolet, Eatontown, NJ 732-542-1000 Purifoy Chevrolet, Ft. Lupton, CO 303-659-8311 South Georgia Corvette, Inc., Thomasville, GA 229-226-4447 SS Racing, Dallas, TX 972-519-3553 The Vette Doctors Inc., Amityville, NY 631-841-0779 http://www.thevettedoctors.com Tony's Corvettes, Gaithersburg, MD 301-869-7110 ZR51 Performance, Cave Creek, AZ 602-319-6575 http://www.zfdoc.com Auto Masters, Bowling Green, KY 270-842-0454 |
Re: New Owners/National list of Z Shops
Thanks! Another great help for the quest to find competent shops. I’ll do some checking and comparison to the current list.
Also, We still need to get this list as a sticky... H :cheers: |
