A synchro is a chamfered ring that helps the two shafts match speeds as one slowly engages the chamfer. If you skip gears, you have a larger disparity in input and output shaft speeds, and that burden is put on the synchro to overcome (additional wear). So by sequentially rather than skip shifting, you make the synchro's work easier.

You can safely skip shift if you double clutch. By double clutching, you manually match input and output shaft speeds and negate the need for a synchro. This is how guys who killed their synchros continued driving and how EVERYONE drove before a synchromesh gearbox.

The beauty of SRM is that it allows a perfect 6-4 double clutch downshift and even does the blip for you.

I have skipped gears for years on my manuals and never had any transmission problems, but then again I'm at low RPM and doing what you call "double clutching" (sometimes pulling in and out of gears without the clutch) 1-3, 3-5, or 2-4, 4-6. I do not do this with hard launches or high RPMS. No problems ever.

Funny thing is they mention the same thing on other car websites and drivers argue they never have problems with the synchros

Just do a search on "370Z Synchro" or the like.
Double-clutching takes all the stress/work off the synchro. I wouldn't think you would have an issue.

A lot of people are complaining of the paint quality...can you elaborate on this? Like orange peel, chips easily on the front end, swirls easily?

The paint is very thin (3 mils) and very soft. I do not have a technical spec for its softness, but I can say that I have seen a TON! of 370Z's on the lots locally, and almost, if not all of them I have looked at already have swirls, scratches, and other stuff. I have never seen this on the camaro's, mustangs, corvettes, etc. The 370Z's just get scratched easier it looks like. Looked at 2 Nissan dealerships, so it's not just 1 bad wash-boy killing cars.

No problems at all on my '09 Base. Nver back to the dealer since purchase---although I've only put 5,100 mi. on her. They only concern I really have so far is the thin paint and I drive very carefully and defensively because it is so vulnerable to chipping, etc. Glad I have the ClearBra.

The thin paint in my experience is more to do with Japanese manufactured cars. I owned multiple Nissan and Honda vehicles and I noticed the paint used by both manufacturers were thinner and more prone to chipping compared to my VW GTI and other family/friends non-Japanese cars like Ford etc.

I bought my '08 Altima coupe three years ago today and its paint remains shiny and perfect. The paint on it is very sturdy, unlike that on my '09 Z.

I wrote the above post after owning my 2009 Z 1.5 years and 5,000 miles. I'm now at 4 years and 12,500 miles. The problems I've encountered are relatively minor and as follows:
1) Thin paint resolved with ClearBra from day one of ownership. Bought the brand new and perfect. She's still perfect and looks showroom new.
2) Steering lock module. The unit never failed on me and was nevertheless replaced preemptively under recall.
3) Inaccurate ambient temperature module-replaced under warranty.
4) Horrific cabin noise-resolved by replacing crappy stock tires with Continentals
5) Sticky back hatch-new springs installed under warranty.
Aside from those relatively minor items, common to the new model in 2009, the car has been fine. I don't track her, so the oil temp has been within normal range in normal daily driving.
Had I to do it all over again, I would, especially as I bought the car at the end of the 2009 model year, cash and no trade, at a price below dealer cost. He was glad to move the car and I was glad to buy at that price, so everyone's happy. I expect to keep the car 10 more years for a full 100,000 miles.
