dave:
as said in this post most companies now buy or lease high cabbed trucks.
the main reason being good resale value or better deals from the leasing companies.
but who buys them second hand ■■?.
i know some smaller firms prefer to buy used and unabused and the rare owner driver may do. but there are thousands of trucks on the roads run 24/7 by the big logistics companies.
are they broken for spares??
do they go abroad ■■?. ive heard many trucks end up in africa and my old daf 75 was destined to be used in a mine somewhere in africa.
but they cant all go there , can they.
For example, the Tesco’s Scania 94L 310 day-cab artics 
. Who would want one of those
