I've bought a set of 18" Carrera five spoke alloys, my Volvo is in the garage, what are the odds on getting the wheels (with tyres) in the back of my convertible 996?
I've managed with 4 alloys in boxes (no tyres) but it was very snug, 2 on passenger seat and 1 on each rear seat. Unless you have a cab then it would be easy.
Might be worth looking into, even if you do squeeze them in you are going to get marks everywhere and probably use more than the delivery cost in fuel.
I've used Paisley freight for wheel collections before with no problems, as have others I know, you just need the sender to play ball and do the wrapping as required for you, I did find the collection details were vague on the timing so the sender had to be at the address ready for 'whenever they turn up'
