Two Mercedes SLKs the white model is by Siku, the silver model is by Welly. They both have diecast bodies and plastic bases. The Welly is supposedly 1/60 and the Siku 1/55 but they are the same length, the Siku is slightly higher because it has bigger wheels. The Siku wheels also have a rubber feel like Hot Wheels real riders. The price was similar the Welly model was 6 lari, the Siku 6 lari 95. The windscreen of the Welly model looks like someone may have stepped on it, the angle is too acute. The detail of the two cars is extremely similar. They are both made in China.
I bought the Siku model because the colouring (white body/red interior) reminded me of the Matchbox Mercedes 230SL, a model I had as a child.
The Siku model also has a license plate in the casting, so of the two I prefer the Siku model, but I like both.
