Pickups are stupid, and everyone will know you are stupid if you drive one 😉
To be fair they are good for what they are designed for – carrying loads off-road – but not much else. Maybe towing huge things. Uncomfortable, crap to drive, slow and very thirsty.
If you want to carry loads of stuff, get a van. If you want to drive fast and have lots of space, get a fast estate. If you want something in between get an MPV. All options that are better than a truck.
As regards the estates I’d still have to get a bike rack and tow bar I presume for four bikes
Depends on how much work you want to put in. You could probably get four bikes in a big estate with wheels and seats off and still seat four. But if you don’t mind a rack why not just fit one your current car? A car with a rack takes four people biking in more comfort and fun than a pickup, and is a fun car when you’re not taking people biking.
