Once you do your major, you don't need to do it every 4 years. Considering the miles we put on our CGT, every 6 years for major service is fine. If your car hasn't done a major service, you should do it now especially for low mileage example you got. I have seen a few CGT with low mileage that never got major service done and when they did, the camshaft needs to be replaced because the valve were never adjusted.

My bill for the major service was around $33,000 including taxes. My tech (shop foreman) charged a flat $6000 for the whole service, with $27000 in parts (including the new clutch at $10000). Even at my special pricing for parts (I get all parts at dealer cost + 5%), it was a hefty bill. Remember, every 12-18 months, Porsche jacks the price up for CGT parts.



I only did my rear diffuser, as everything else on my car is fine. All CGT diffusers will need to be re-cleared at some point, they are all bad and will delaminate over time, especially the area around the top edge (under the exhaust tip area) and all of the screw areas. My local Ferrari body shop did the re-laquer for me for FREE (I ended up buying them a case of cheap whisky for their trouble). They did put 12 coats of clear on it, as the carbon is porus and sucks in a lot of clear, so you end up with a lot of these dimples if not enough clear is put on. It's a tedious process, clear, sand it down, clear, sand it down, etc. To do a good job, the process takes time and patience.



You can fix the synchro, but nobody I know of here in the US has done a CGT gearbox. If you lived in the UK, they just send the gearbox back to the original manufacturer (a local UK supplier) and they can fix it for cheap. Synchro is weak on the CGT, and Porsche's official response is that you replace the whole gearbox when synchro goes out. And if you try to open one up, you can't return it as part of the core exchange. I think the retail price on the gearbox is around 39K, assuming you return your original gearbox as part of the core exchange. Add 11k more to the bill if you want to keep your gearbox.

You shift into 3rd gear when the car is cold. On the CGT, I wouldn't try to mesh into 2nd gear unless you are going full throttle. At full throttle, the gearbox comes alive and everything goes in like butter. On partial throttle, I would go from 1st into neutral slightly and then into 2nd gear.
