In my opinion the i8 now compared to the LC500 is a step backwards in styling and driving experience. The major problem I found was getting in and out of it when you had cars parked either side of you. The gull wing doors were very restrictive, and it didn't matter how far away from everyone else you would park, someone would end up parking right up beside you, sparking a whole host of gymnastic moves to get in... Parking issues aside, although I didn't have a problem, if you are less than supple, getting in and out over the thick door sills could be an issue for some.
The interior was typical BMW and nothing special. It drove really well and was a complete rocket ship and with the addition of AWD stuck to the road like glue. The 360 degree camera was a great feature and I sorely miss this in the LC. No BSM or adaptive cruise in the i8, both features I like in the LC. Despite being really well priced now to buy 2nd hand there are still very few i8's on the road, I think the realisation of the impracticalities of the daily use of this car is beginning to become common knowledge.
