A lot of these are novelties clearly built tongue-in-cheek just for the sake of it, and I don't think deserve the flak they're getting.
Also, providing the conversion is sympathetic, subtle and proficient who doesn't love a massively powerful engine swap into something unassuming? "Sleepers" are some of the best modified cars IMO.
For me the most pointless and impractical vehicles are the growing raft of "high-end" / performance chelsea tractors and soft-roaders being cynically shat out onto the market. Needlessly large and heavy high-rise icons of crass conspicous consumption that are often only driven in urban environments and sacrifice materials, fuel consumption, emissions and other road user's safety, visibility and space just to satisfy the owner's mis-placed subservience to an totally false and manufactured ideal of what constitutes "success".
Yes but some of them offer some nice comfort for the journey, Mini or a Range Rover for a long journey I know which I would go in. Having said that I dislike both.
