It's reliable, of course. Also it's repairable, you can find parts for repair in every place in Russia, and many countries which had been is Eastern Bloc, because it was sold there before 1991. Also repair parts are dirt cheap, really, even me can afford them and I'm poor as church mouse. And you can repair it in every place, because it's easy as can be.
Also, it's a beautiful design. But it's my personal opinion. And it was constructed in USSR, it also matters, at least for me (because everything is what constructed in post-1991 Russia is crap - Soviet = Best in the world, at least for me).
Also - it's rear wheel drive ,it's means that you can drift it in every place you want (it's very fun actually), especially if it's winter. Also classic Ladas is having huge potential for tuning, yes.
And anyway I love my car, I'm not going explain it further. At least it's not against me, like the world I'm living in.
