A guy I know and am facebook friends with is making a rather interesting video game where you assemble and tune a Datsun 100A. The game is called My Summer Car. It seems to be set in the early 1990’s Finland when the Datsun 100A was a popular car for youngsters to learn car stuff with. We used to drive one of those around a frozen lake with my cousins.
Here’s some video about it:

looks like a lot of fun
I can see this becoming quite popular. The sequel has got to be Pimp my Peugeot 
Heh, that actually looks like it might be quite fun. The list of features on the website is pretty good.
A few gaming websites have now noticed this game, and not only in Finland. A long youtube video has been released where the maker of the game talks about it, with quite terrible (but entertaining!) rally driver english. youtube.com/watch?v=r0IZ_TEzg7M
I have a test version of the game and I’m going to stream it on twitch tonight after the Finland - Russia ice hockey game (so around 22:40 UTC+2 or +3, I’m always confused about the time zones) twitch.tv/dukeaccent (If I talk at all, it might be in Finnish, although if many people from other countries will watch I can probably manage to make myself understood in English as well)
I haven’t watched the dev video yet - [edit: from the two videos in the OP,] the thing that it reminds me of most is Car Mechanic Simulator 2014, and that’s a pretty cool thing. Thanks for posting about this!
