To expand on Neils answer I only use 1/87 vehicles and accesories on my two ongoing projects, with the exception of an old EKO Ford Thames which is 1/86. My pet hate is the use of Cararama models which are nominally 1/72 a cararama mini alongside an EFE bus quite frankly looks ridiculous. It is my belief that 1/87 vehicles are a better option than 1/72. In addition many modern trucks use similar design cabs so if you buy the biggest in 1/87 it will pass as the medium one in 1/76.
Just my view
