11/10 game
This is probably one of the best games I've played.

The graphics aren't the greatest, sometimes there's a glitch or two and the overall idea is fairly simple.
None of these things matter though as that simple idea is pulled off really well, with a good amount of difficulty and a lot of depth.
Unless you're an absolute whizz or have a lot of time to spare you'll probably find yourself bouncing around the wiki quite a bit in order to get the car going and do some of the other stuff there is to do.

Building the car is just the beginning, the game intertwines other things you can do really well by offering jobs that help you earn money for car upgrades and repairs and a few other fun events and interactions too. Everytime I've picked up this game since owning it, I've learnt another little thing about it or found something new to do.

The eye for detail in certain places is just a joy to see. It's clear the developer has a passion for the game and it shines in the wonderful little details other games would miss.

It's really hard to put into words the feelings I have for the game, it's annoyed me so many times and I've died and started over on permadeath more times than I can count... but I always come back and keep going.
A friend of mine said it best - "The Dark Souls of car building".
It's maybe not quite that difficult but on permadeath there's certainly numerous ways to end a run lol.

So far every friend of mine who has played the game has enjoyed it, whether they knew a bit about cars or absolutely nothing.

Strongly Recommend.
