The cheapest price category is suitable for you who aren't exactly sure just how fun driving feels but this category has some good options too.
The cars in this price category are surely better than the cars you'd find at your local everyday store but they might not meet all the requirements we have for a hobby-grade RC-car. If your previous experience is limited to the everyday store stuff the performance of these cars will surprise you positively and you have a great chance of being able to drive these for multiple years to come. In this price category the Absima's 1/16th and 1/14th scale cars give you an especially good value for the money and are full blown hobby grade vehicles with spare parts available, good off-road capabilities, the option of limiting the power and performance that will surprise you.
The Absima's cars available at under 100 euros give you insane value for the money. The performance is surprisingly good and these cars will be sure to beat out any toy-grade RC-cars without a doubt. You can also get spare parts for them so in case of a bigger crash you can still repair the car afterwards. This means that you can use the same car for quite a few years if you take good care of it. (A tip for parents: A hobby grade RC-car with parts available is a good way to teach your kids about care, responsibility and dexterity.)
For just over a hundred euros we've got tiny crawlers from Carisma and Axial. These small crawlers are very off-road-capable and are really fun indoors or on some suitable outdoor terrain. While thes speed of these isn't anything crazy, these little off-roaders can climb like no other!
