If it were me, I'd look into a Tesla. Get right up to $50k. Then turn around and sell it for $55k (do used ones still go for more than brand-new ones?). Alternatively, get a vehicle with a bunch of tax rebates/credits/etc. Depending on your state of residence and vehicle you choose (and your tax liability), you can get over $10k back on your taxes next year. Double-check everything, some tax credits come off your personal taxes, some can come off the sales price, I honestly haven't looked into it that deeply.
In fact, if it were me, I'd probably try to get some electrical work done "for free". My electric panel is maxed out and I had to take out the 30amp breaker for the dryer so I could put in a 20amp breaker for our electric vehicle. If someone else was footing the bill...I'd have them put in a whole new panel with plenty of extra slots for future breakers, go ahead and wire it for a generator (nothing to do with the car, but if they're already in there doing the wiring...), I'd even have them wire up both sides of the garage so there's somewhere to charge a vehicle regardless of where you park (or perhaps one outlet in the garage and one on the side). Don't forget the EVSE. I think there may be a tax credit on that as well, check into it.
If after you've picked your electric car and have gotten a quote on the electrical work, you still have funds left over to spend (don't want to leave any on the table!), now may be a good time to look into solar? An extra, say, $10k to go towards a solar install would pay dividends down the line. Plus, again, I think there is some kind of tax credit for that. Double bonus (or triple bonus, since you get free electricity, a tax credit, AND an increase in home value).
