The clicking noise doesn't sound excessive to me and feels like normal DI noise, but I'll let the real experts chime in.

Don't forget to always put good gas in

Thanks for the Table! That’s some great input!
I already thought that it might be the engine just cutting spark to ensure the high pressure oil pump can provide lube to the engine. According to the table everything should be fine with the starter, regarding the starting times. Maybe it’s a little bit prolonged but not much.

As for the noise, I will check back on it again in a month. If it gets worse, I will upload another short video. Thank you!

3) Weak battery/temperature
4) Chevy quality again, mine started to peel like 6 months into ownership

And here's an extra one, if you are driving highway speeds, say 80+ kmh on 6th gear and you're around 900-1100 RPM and accelerate, the car will make this low rumble that sounds weird and disappears, THIS IS NORMAL, IIRC it is the resonant frequency of the car but don't quote me on that

I will try with higher Octane fuel. So far I only filled it up with ROZ95 which would be a RON91 in the US, I guess..it will be empty soon and I will fill it up with Aral 102+ High Octane fuel and I will see what it does then.

As for the low rumbling noise, I know thatcher is normal and I don’t worry about that. Thanks for the heads up though! I usually don’t drive in such low RPMs to be honest.

Thanks for the other inputs, as well! The DI Noise is the one thing that worried me the most but so far it seems normal.

And agreed - München is a beautiful city!

I usually drive in Touring-Mode. I only tried out Track a few times on the Autobahn so far. I really do think that it’s bad fuel, and the engine cutting timing in low RPM, high power demand situations to prevent knocking.

And thank you! Yes, Munich indeed is beautiful! I love it here! I’ve been to the states 14 times and it’s always a blast but I always come back and feel glad to be at home here.

Thank you so much for your compliment! My English is a bit rusty, indent really use it as often as I want to.

Having said that, GM V8s are torque monsters that pull hard even below 2000 rpm.

However, if you are accustomed to turbocharged cars with flat torque curves, you are understandably concerned. People talk about turbo lag, but in fact, turbo cars pull harder at low rpm.

That could be a thing too! I work for a service provider for BMW and my last car was a Golf GTI so I am very used to turbocharged cars and never had a NA engine with this kind of displacement or power. Though I still think it’s an timing issue and I want to see what it behaves like with high octane fuel. Because the effect from 1500RPM to 2500RPM is extreme. It also sounds different so I really think it’s cutting timing.

Not to steal your thread, but how prevalent are manual transmission cars in your part
of the world? In the USA, manual transmission new cars are becoming rare. The
majority of drivers here cannot operate a manual car. How does this compare to Munich and Germany?

Thank you! And no worries! As mentioned before, I’ve been to the States 14 times now and I’ve never seen a manual in the U.S., only in enthusiast cars or performance cars.

Here in Germany manuals only really became a thing since VW launched the DSG in it’s Models back in… let’s say 2010.
Before that, automatics were a thing only really well equipped or high performance cars had. You can still get a lot of new cars as manuals. Only high performance cars are usually limited to automatics. Though, BMW just launched a campaign with the New M3 and M4 to save the manuals! But it’s getting less and less here when it comes to new cars.

When it comes to Camaros, I would say it’s a 80/20 split. 80% being autos.

Used cars are often manuals and people like my parents and grandparents, won’t buy an automatic. They‘re so used to manuals, they won’t change that.

Oh looks great! I will see if I can find something similar on German eBay
How did you get the old lettering off so well?
And how does the extra strut bar feel? Is there a note able difference?


To all: Thank you so much for your input!
I am a lot less worried that I might have bought a less nicely treated or just not as good car as I thought I have.

One last thing that came to mind over the weekends and driving the car for a bit:

The clutch feels a bit weird sometimes. And with weird I mean the engagement or gripping point is kinda weird. First when you press the clutch, there a bit of a dead zone, then there’s grip, and then you kinda fall into a like a void.

Is that “normal” or might the clutch be a bit worn out? I bought the car as the third owner and 45.000km or around 27.000 miles on it.
