LEGO is indeed pretty expensive these times. Not every set is that bad, but the most cars are not only expensive, but not even the best sets on the market...
There is a lot of comparisons, but the most convincing one maybe the LEGO Ferarri (42125) vs. CADA Italian Super Car (C61042W) video[1] of "Held der Steine" (german youtube channel). The LEGO is "parts only" - the CADA is remote controlled with led lights near double the parts of the lego one for the same price.
Many of the newer manufacturers are 100% compatible and provide near double the part count for a similar set. Even if some of them are shameless rip-offs and illegal to have in some countries, most of them are smaller companies with great part quality, prints (no stickers) and innovative designs (see CaDA® C61503W AMG One).
There is also the world of Trains or Tractors, where LEGO tends to fail every time.
There are
- CaDa
- BlueBrixx
- Cobi
- fischertechnik
- Unico
- Mould King
- burgkidz
- Wange
- Sluban
- Q-Bricks
Just to provide you some alternatives :-)
