Handheld scopes for low speed work like this are remarkably cheap on ebay. Probably not accurate, but for automotive work you just need to look at simple pulses.

Absolutely! I bought an open source one - An MP3 player, which can be converted to a full colour storage scope, reusing the screen + case and other parts, with a specially made PCB and software. It is very accurate and I flagged it up on this forum as a good buy for diagnostics on cars, at the price. It has doubled in cost since then.
