So, not really a repair question per se.

Thinking of picking up a 4th or 5th gen accord to have as a spare car ( and because it would be fun).

In terms of reliability, is there one that stands out? I know how the car has been driven and maintained matter greatly but assuming that its low miles and hasn't been driven hard?

All I know is my 6th gen.

 

id go with a 4th gen because i like the way it looks
also it doesnt have a chip key, so youll never have that problem
the front end on a 4th gen looks very good
kinda like a small gtr 34 its timeless
the motor and suspention on both cars is the same thing

but the 5th gen to me is just a normal car that you see everywhere so its not very unigue
just like the camry from toyota

 

Jump to 6th and get a manual.

 

But I already have a 6th gen! haha.

 

I'd say both are just as reliable as each other. At this age service history and good maintenance would be most important.
