I saw this discussion cross posted onto Oppositelock. While it is clear that the author is not a gear-head I do want to give him or her credit for two things 1. getting a used car inspected by a mechanic before buying and 2. getting multiple quotes for a repair. However what struck me is not once in the post was the make or model of the car mentioned. So that got me thinking, we all know plenty of non Jalops that ask us for advice, and you know the saying "teach a man to fish...and something, something." Anyway, what knowledge should non-Jalops know? I think the basics should include: year/make/model of their car, what engine they have, how to find the tire size, and what gas is recommended for that specific vehicle. Anything else?
