I had the BJ-212 jeep (a rebuilt of the UAZ 469?). Fine and detailled, but compared to my 1/18 soldiers, the vehicle seemed closer to a 1/20th scale, so I sold it:

The more recent BJ-2022, Humvee clone, has perheaps a more accurate scale and match better with 1/18th figures, with still the same quality and détails:

.
Now, this new armoured light vehicle is promising, but the price... and who can tells what real scale it is?... I won't buy it, too much risk if it's not an accurate 1/18 scale.
By the way, the accuracy of 1/18 die-cast vehicles is a real problem. The Maisto Humvee seems more 1/22, I also found a Navy Seals desert buggy and it was really too big (even bigger than the PTE one, as I remember, more 1/16, making my BBI LAV ridiculous).
