I did a quick google search about automotive oscilloscope videos. This guy does interesting things:
https://www.youtube.com/@MechanicMindsetHe's using different devices ranging from a DSO138 to a picoscope 2024A. Unable to find any videos about automotive grade picoscope or micsig oscilloscopes. He doesn't seem to need any special automotive feature.
With a very very high probability, DSO 138 is really the cheapest toyscope in the world. Here's the video:
Recommedation is for picoscope 2024A, I could get it right now for €138 from mamazon . It's a 10-MHz oscilloscope. Here's the video:
Another channel, video about a "Secret $150 portable Automotive Oscilloscope Labscope". That oscilloscope has a "FNIRSI" branding on it. FNIRSI oscilloscopes are nothing to write home about. But, hey, if 10 Mhz are enough and signals are above 0.5 V, then even my zeeweii dso154 will serve me well. I would like to have CAN decoding on it however. The video:
If youtubers are using those devices, it doesn't seem that neither broad bandwidth, huge memory, nor high sensitivity, are essential. Cheap grade oscilloscopes are already useful. Then, an automotive grade oscilloscope, either from picoscope or micsig, will probably look and behave like a jet fighter in comparison. I bet that would be a kind of pro badge, like using a fluke DMM. The guy in the video speaks about a 1000 pounds price for one of these automotive grade picoscopes? I guess you'd be able to find a similar-capabilities micsig in that range. I would contact a seller and ask about it, if no good info is found on the Net.
IIRC, there was a thread about a guy using an automotive micsig, that had problems about a BNC connector getting loose from mechanic action. So you could be looking for models with recessed or somehow protected BNC connectors.
I would be wondering about pro automotive grade or not, and about laptop needed or not.
In your price range I could get from micsig.es either:
SATO2002 for €650+VAT, touchscreen+knobs, 2 channels, 200 MHz, 1 GSa/s, 70 Mpts memory, decodes CAN.
VATO2004, €500+VAT, picoscope-like, can be connected to and android tablet/phone, 4 channels, 200 MHz, 1 Gsa/s, 50 Mpts memory, decodes CAN Edit: that spec seems a little too much? I would say 100 Mhz for 1 Gsa/s and 4 channels?.
Anyway, compared to a 1-2-channels devices boasting 10 MHz, 4Kpts memory, these are jet fighters. I'm sure picoscope will have something similar.
Then I would open a new thread about the candidate, mentioning automotive use.
