This might get a bit Technical

Just to help out my buddy Ferry a bit :)

I have more in storage, just not in easy reach, so this will have to do for now.

1. S&S Lada Riva saloon car. Super generic resin car, fits in everywhere and as everything. Taxi, police car, civillian, car, target car. S&S even makes African and Arab half figures to glue on the windows for a drive by. S&S Lada Riva Currently retails at 6.50 UK Pounds. Single cast with 4 metal wheels. Casting is typical for S&S, so be prepared to fill in the air bubbles with some greenstuff. This one is painted as a Yugoslavian decoy for aicraft.
2. Same S&S Lada Riva saloon car, this time painted up as generic TV crew car, fitting for any warzone since the 70's
3. JB Models (now Airfix) Landrover. Plastic kit, you can buy a verson with a hardtop or a soft top, and they come with a trailer, which is supereasy for loads of armies. Price varies from a couple of euros second hand right up to some stores asking as much as 15 euros for a single kit (which is a bit ridiculous ans a proper diecast can be had for half that). Again, super generic, as a civvy, Technical or as these 2 WIP's, British Special Forces rides for the Cold War.... I really should finish those someday, even though I'm no longer in big scale Cold War conflicts, they would be very handy for TW:2K
4. Same as 3, but with AT asset, The other one will get a minigun, thx to a former SAS friend who wants to remain anonymous.
5. Hobby Den Toyota 4x4. I have a ton of these, all based up and ready to go, just paint them black, add a magnet in the back so I can slide on a Back off sign in Arabic, add a magnet in the roof so I can put a MMG/HMG/Minigun/Grenadelauncher on it. They are meant for my Blackwater project, but can double as unmarked black cars for any location and any faction, be it intelligence, government, drug lords or warlords, anything goes really. Very affordable too, these are currently priced at 6,50 euros for a single resin cast with 4 resin wheels.  Hobby Den 4x4 Toyota  Bryan also does a Technical version of the same vehicle, I reviewed that back in 2012: Hobby Den 4x4 Technical
6. This SUV is made by Britannia/Grubby Tanks, and would be a very good deal at 6 UK Pounds each, as it comes with 2 Taliban and a 12.7mm Dhssk. It has 4 metal wheels and the veicle itself is a single resin cast. Therein also lies the problem, as in the last few years I've been let down by the terrible casting quality from Britannia's caster. Having said that, this is a very smooth model, nothing like the hard cornered armoured vehicles, so it could be less affected. Although sold as Taliban, there is nothing stopping you from using this as a Special Forces ride. Afghan Technical
7. RH Models aka Liberation Miniatures Technical. Very nice ride, but due to getting my entire country blacklisted by our benevolent Dictator Rolf Hedges, no longer available to us. Included for completeness.
8. Britannia/Grubby Tanks M35 truck. Really old casting, upgraded with a aluminium tubing exhaust to bring it up to M35A2 specs, and a miscast BRDM-2 hull, cut down, added in the back, as a makeshift convoy protection vehicle for TW:2K. I didn't like the way it was going with my add on door armour, so took that all off and forgot all about it. Suitable from Vietnam up to present day, as a Government or Rebel vehicle, easily converted and less costly then the Academy M35 truck. But yeah, their current castings are shite so order at your own risk. Britannia/Grubby Tanks M35 truck
9. ICM ZIL or Jiefang truck - I picked up a dozen or so of these way back when shipping was still affordable for less then 4 euros per truck. Pretty generic truck, multi role use, civillian to military, plastic so easily converted by adding drop in loads or a baby wipe tarp.
10. RH Models Saxon. Also added for completeness, I picked up some second hand ones for use with TW:2K and was surprised a few years ago when Ukraine got about 2 dozen from the UK to help with the war effort.....and that was the last thing I ever heard or saw about them. Not really a Technical but makes for a great militia/marauder vehicle.

Now, there are a lot more Technical suitable vehicles available in 20mm. I've made a order with the Hobby Den as well as some samples to paint up for their shop,  and like I said, I have loads in my stash I need to dig out as well, but that is for a next installment.

Now, comparing these to diecasts, the diecasts are of course much cheaper, especially when bought second hand. The wheels tend to be a bit of a let down, but you can always rip them off ond base them on suitable resin wheels. Shape wise, they tend to be a bit hit/miss, I've got more then a few who look suitable but when measured up, turn out to be way oversized. Caveat Empor, bring a 20mm fig with youy when shopping, I say.

Hope you find this helpful.
