I was on the market for a GX470 but with thr insane prices I think I should just go with the GX460. In terms of reliability and maintenance, I've heard of the water pump and timing chain cover leaks, and something regarding the spark plug socket. For current owners, what are things you had to fix and I should look after? I'm also thinking buying remotely but not sure if this is a mistake since it would be my first time buying a car I have not driven.
