Not too many. I think I can eliminate 99% of the females I know and at least 75% of the males I know. I kind of like changing the oil in our many vehicles. I do it once a year. I enjoy working on vehicles but with many of the newer models it's tricky unless you have the right tools or scanner.

My favorite car for working on that I ever owned was an early 1970s model Toyota Landcruiser. Back when Landcruisers looked and drove and rode like Jeeps. Pretty similar to this, except all white and we didn't have locking front hubs. (The front tires were always locked and so that the front driveshaft was always spinning. But the front driveshaft was engaged to power only when the transfer case was in 4WD.)
Everything on that car was easy to get to, with lots of room in the engine compartment, under the chassis, and around the wheels, and did not require any special tools. It was evident that the car was designed for ease of service.
We bought it in the fall of 1974, just after we were married and we were living near Blue Jay, in the San Bernardino Mountains. The 5280' contour shown on USGS quad maps went right in front our house. We bought it to be able to get around in the snow; two-foot snowfalls were pretty common at our house, as were just over the rim, in the highest precipitation area in the San Bernardino Mtns.
I was working in downtown San Bernardino, driving down and up Highway 18 almost every working day. When it got really bad, I would chain up, and then we could get around in almost any conditions as long as we had clearance underneath. I particularly appreciated the added steering traction I got from chains on the front tires. With all of the space in the wheel well, putting on chains was a breeze. I could fully chain the tires in less than five minutes.
