If you were worried the leaf was going to be the end of DIY EV conversions, what about the Renault zoe (Nissan is part of Renault).
It's 15000 EUR in most of Europe (20000 - 5000 EUR bonus for anyone), it has a 130 miles range (real range will be around 100 miles, which is better than the 60-70 miles of the leaf) a 135km/h top speed (84mph) and is compatible with quick drop and 3 phases fast charging (30min for 80%, 1h for 100% with extremely cheap and simple plug(no electronics))
The catch?: The 24KWh battery is leased (starting at 80 EUR/month).
I'm getting one in September, at current Lithium battery prices, the leasing is pretty cheap but as batteries prices decrease I think a DIY battery will do wonders (lower price and/or increased capacity)
If I look in the french EV market, there is quite a few used 10 years old EV for sale without batteries (such as the Peugot 106 Electrique, Citroen Saxo EV, Renault Kangoo EV...) - the battery were leased back then (for ~120-150 EUR/month) and the range was pretty bad (~50 miles) - for a DIYer, such a car is great as the only thing you have to worry about is the battery, everything else work. Those car were not using lithium batteries at the time so I'm pretty sure you could get a 70-90miles range just upgrading to li-x!
I think those "new" cars will enable DIYer to do wonders (especially with new EV specific parts being available); I don't think this is the end but more like a new beginning
