A few observations from 3 years experience buying a used 2012 Leaf - with a replacement Lizard battery:
1. Solar charging of the "traction" battery requires a substantial PV array. To get about 10 miles/day additional (on a good sunny day) requires a couple of the largest, most efficient XL panels that are each 3-1/2 ft by 6 ft.
2. In the Houston, TX area, almost all the "free" chargers were either not working or not free anymore.
3. Leaf Spy is an absolute necessity for me to estimate trips around Houston. 30-50 mile trips are usually a no-brainer if I plan ahead and charge to 80% charging. 65 miles plus, I need to plan on a charge station stop - even with an overnight 100% charge. Of course, this changes over time with fairly rapid battery degradation.
4. I bought a replacement set of tires over a year ago. Bought the cheapest I could find at Discount tire on their Labor Day special. Quite happy with them. If you search this blog, you will find many good recommendations. IMO, any tire Discount sells is likely Ok for the type of commuter driving I do. Just need to keep the pressure at the max allowable.
5. The dirty front compartment seems unusual. I've looked at many used Leafs and they were all very clean - probably because there is not oily fumes, spills, etc. Maybe a dusty environment? If that is the case, it would seem that a careful spray of simple green/soap solution and light application of rinse would clean it up?
6. Any good alignment shop should resolve that issue - although I've never had any issue with uneven wear.
