Can't see them giving you the bigger battery for £5k. Think it'll be a straight swap of 24kWh one.Clever to leak the news of the "250" mile range, backwards compatible pack available in 2016!
Although this may well put a floor under the prices of older Leafs, since the big unknown with them was the battery pack and that uncertainty is now gone.Not so interesting right now, but as and when an improved pack is launched it could be tempting. In another year a 60k+ Japanese Leaf will probably be £5k to buy, if you're able to upgrade that to a 30kwh battery it's not bad for £10k.
With brexit eminent, parity between pound and euro is expected. Modi companies round off and we tend to get a raw deal compared to $ and €£5,000 is not €5,000 is not $5,000, speaking as a Brit I do wish companies wouldn't do that.
The point raised above is very valid, for many a replacement car may work out cheaper, or similar, but I think Nissan's decision to offer this at all is very positive for current owners (more so than prospective ones) and shows some goodwill.
