Miatas are pretty underrated in that regard - on the 1st gen (~1990) you can reach about everything without taking anything else of. Jobs that would take days (or hours in shop setting) to do on other cars take under 30 mins on the Miata. Notable examples are starter and brake booster - they are "right there", with a ton of space. You can't even get to the spark plugs easily on a lot of cars these days. (heh, "these days", now I sound old)
